Abstract

This paper presents a software defined radio (SDR) implementation based on programmable digital signal processors (DSP) for smart antenna systems (SAS). We evaluate adaptive beamforming algorithms, namely non-blind-type least mean square (LMS) and blind-type constant modulus (CM) using TI TMS320C6000 high performance DSPs for cdma2000 reverse link. Adaptive beamformers are implemented using TI code composer studio (CCS) that includes assembly language and C code development tools. Performance variation of these sofware radio beamformers in terms of weight computation time and received SINR are compared for different C6000 development boards (TMS320C6701 EVM, TMS320C6711 DSK, and TMS320C6713 DSK) and array topologies under varying multipath propagation conditions. Results show that while antenna array and algorithm type are important for the SINR performance, DSP type becomes important for the weight computation time.
