Abstract

A novel evaluation of filtering and quantization losses for weak DS-CDMA receivers is presented. Using this method, joint optimization of filter center frequency and bandwidth is conducted for one-, two- and three-bit quantizers. It is demonstrated that a joint loss-analysis of these effects is necessary to optimize front-end design.
