in order to compensate for performance degradation caused by inferior low - cost analog radio component tolerances of an analog radio , a wireless communication transmitter employs a control process to implement numerous digital signal processing techniques to compensate for deficiencies of such analog components so that modern specifications may be relaxed . by monitoring a plurality of parameters associated with the analog radio , such as temperature , bias current or the like , enhanced phase and amplitude compensation , as well as many other radio frequency parameters may be implemented .
