In order to compensate for performance degradation caused by inferior
low-cost analog radio component tolerances of an analog radio, a future
system architecture (FSA) wireless communication transceiver employs
numerous digital signal processing (DSP) techniques to compensate for
deficiencies of such analog components so that modern specifications may
be relaxed. Automatic gain control (AGC) functions are provided in the
digital domain, so as to provide enhanced phase and amplitude
compensation, as well as many other radio frequency (RF) parameters.
