Design of a CDMA Reverse Base Filter Based on AD6624

()

Abstract:

This paper gives the design of base band signal processing in CDMA reverse link. The design is based on the models of wideband digital intermediate frequency and Digital Down Conversion(DDC) in the Software Defined Radio(SDR) and uses the principle of the signal processor AD6624 produced by ADI. The design of the base band filter and its simulation result are also included.
