Sample rate conversion for a software radio receiver is one of the critical tasks. Due to the phenomenon of bandpass sampling, digitization of a very high intermediate frequency incorporating different wireless communication standards has to undergo sample rate conversion ranging from a factor of 4 to 400. In this paper, an architectural implementation of Digital Down Converter (DDC) for multi-standard...
Software defined radio (SDR) seems to be a solution for communications for rapid changes in the communication standards. The two most computation and resource intensive tasks in the design of receiver for Software Defined Radio (SDR) are Sample Rate Conversion (SRC) and Channel-ization. Cascaded Integrator Comb (CIC) filters are suitable when Sample rate change by a large factor is desired. However,...
