methods , systems and receiver devices are provided which may provide improved receiver performance in obtaining estimates of the complex - valued baseband channel in the presence of colored baseband noise . in various embodiments of the present invention , systems and methods are provided in which , over each synchronization signal period or other determinate information window , the channel coefficients and the color of the baseband noise are concurrently estimated . thus , both the channel coefficients and the color of the noise are estimated , rather than assuming white noise , and channel coefficients may be provided that account for the color of the noise these estimates may be provided for each burst of a communication and may result in an improved channel estimate in the presence of colored noise . the baseband noise can become colored due to , for example , having a non - nyquist receive filter , due to the presence of a colored co - channel interferer , or due to the presence of an adjacent channel interferer . the concurrent estimates of the color of the noise and channel coefficients may be provided iteratively or by selection of a best result among a plurality of candidate noise color assumptions .
