Abstract :
Nowadays the performance of ADCs still cannot fulfill the high requirement of the wideband receiver, in this paper we are motivated to solve this problem by proposing a parallel A/D scheme in the cellular base station with uniformly distributed channels. This scheme adopts multiple parallel ADCs with low sampling rate and high resolution degree to fulfill the requirement of both high sampling rate and high resolution degree. We believe that this scheme offers great practical value for the software radio system design under state-of-the-art technology.
