in the following description , numerous specific details are given to provide a thorough understanding of embodiments . the embodiments can be practiced without one or more of the specific details , or with other methods , components , materials , etc . in other instances , well - known structures , materials , or operations are not shown or described in detail to avoid obscuring aspects of the embodiments . reference throughout this specification to “ one embodiment ” or “ an embodiment ” means that a particular feature , structure , or characteristic described in connection with the embodiment is included in at least one embodiment . thus , the appearances of the phrases “ in one embodiment ” “ according to an embodiment ” or “ in an embodiment ” and similar phrases in various places throughout this specification are not necessarily all referring to the same embodiment . furthermore , the particular features , structures , or characteristics may be combined in any suitable manner in one or more embodiments . the headings provided herein are for convenience only and do not interpret the scope or meaning of the embodiments . the ofdm receiver 100 shown in fig1 receives a complex digital baseband receive signal at an input 1 . input 1 is an input of a frequency offset compensation unit 2 . the compensated signal from frequency offset compensation unit 2 is fed to a guard interval removal unit 3 . after removing the guard interval , a fast fourier transform unit 4 converts a block of received samples into corresponding frequency - domain symbols . a phase error estimation unit 5 performs phase tracking on the signal from fast fourier transform unit 4 . furthermore , the receiver includes a frequency tracking loop filter 6 . the common phase error , i . e ., the average phase rotation in the complex plane from one ofdm symbol to the next one , is estimated by the common phase error correction unit 5 , and the calculated phase delta is used as an input for both phase tracking in a phase error integrator 7 and a phase error compensation unit 8 and frequency tracking in frequency tracking loop filter 6 which adjusts the compensation frequency value at the frequency offset compensation unit 2 . for phase tracking , the phase delta is accumulated in phase error integrator 7 and is used as a compensation phase in common phase error compensation unit 8 . then , the channel transfer function is estimated in a channel estimation unit 9 and is used to demodulate the data in a demodulation unit 10 . demodulated data are fed into a combined de - interleaving and error correcting decoder 11 to obtain the received data at an output 12 . in dvb - h , this combined de - interleaving and error correcting decoder 11 typically comprises three layers , a bit and symbol de - interleaver with a viterbi decoder , a convolutional de - interleaver with a reed - solomon decoder , and a large block de - interleaver with a second reed - solomon decoder . a fast jump of the down - converter frequency in the dvb - h receiver depicted in fig1 causes only a slow adaptation of frequency tracking loop filter 6 . as a result , the frequency offset is compensated only slowly in frequency offset compensation unit 2 . this results in a large number of ofdm symbols being severely affected by inter - carrier interference . this may result in erroneous receive data and visual errors or dropouts of tv reception . the embodiment of a system 200 shown in fig2 comprises a frequency jump detector 13 , a frequency offset estimator 14 , and an exception controller 15 which runs a state machine triggered by a detected frequency jump . frequency jump detector 13 compares the absolute value of the estimated common phase error with an adjustable threshold . if the threshold is exceeded , a frequency jump has been detected and the exception controller state machine 15 is triggered . the following actions are taken : frequency tracking is turned off , keeping the last compensation frequency value , and common phase error estimation is turned on in case it was not used by default . once the frequency jump has settled , the frequency offset is estimated based on the phase delta between two subsequent ofdm symbols . then , the estimated frequency offset is added to the last setting of the compensation frequency , and the summed value is adopted as the new compensation frequency . once this new value has been set , frequency tracking is switched on again . during one cycle of frequency jump exception states , the time - interpolation across several ofdm symbols within channel estimation unit 9 may be adapted such that corrupted ofdm symbols which contain severely distorted pilot symbols are considered only as little as possible for channel estimation . the purpose of this is to provide an as clean as possible channel estimation for all ofdm symbols during the occurrence of the jump . during one cycle of frequency jump exception states , the demodulation may enable dedicated algorithms within demodulation unit 10 which improve reception in presence of inter - carrier interference , such as an inter - carrier interference subtraction . in one embodiment , the occurrence of a carrier frequency jump is detected by comparing the absolute value of the common phase error between two subsequent ofdm symbols with a defined threshold . in another embodiment , the amount of frequency offset is estimated by multiplying the estimated common phase error between two subsequent ofdm symbols by a value , which may be an implementation specific constant . in another embodiment , time interpolation within channel estimation unit 9 is adapted in a manner such that those ofdm symbols which are severely distorted by inter - carrier interference caused by the frequency offset are as little as possible considered for channel estimation . in another embodiment , demodulation is controlled such that dedicated algorithms are enabled which improve reception in presence of inter - carrier interference , e . g ., an inter - carrier interference subtraction . the embodiments discussed herein may find application in mobile phones , personal digital assistants ( pda ) and generally in any orthogonal frequency division multiplexing ( ofdm ) receivers . the detailed description has set forth various embodiments of the devices and / or processes via the use of block diagrams and examples . insofar as such block diagrams and examples contain one or more functions and / or operations , it will be understood by those skilled in the art that each function and / or operation within such block diagrams , flowcharts , or examples can be implemented , individually and / or collectively , by a wide range of hardware , software , firmware , or virtually any combination thereof . in one embodiment , the present subject matter may be implemented via application specific integrated circuits ( asics ). however , those skilled in the art will recognize that the embodiments disclosed herein , in whole or in part , can be equivalently implemented in standard integrated circuits , as one or more computer programs executed by one or more computers ( e . g ., as one or more programs running on one or more computer systems ), as one or more programs executed by on one or more controllers ( e . g ., microcontrollers ) as one or more programs executed by one or more processors ( e . g ., microprocessors ), as firmware , or as virtually any combination thereof , and that designing the circuitry and / or writing the code for the software and or firmware would be well within the skill of one of ordinary skill in the art in light of the teachings of this disclosure . when logic is implemented as software and stored in memory , logic or information can be stored on any computer -
