Abstract :
In this paper, we compare and analyze the SINR performance and convergence behaviors of various TRB algorithms, which are applied to wideband CDMA reverse link systems. The cases of low-rate date service (e.g. voice) and high-rate data service (e.g. image) are considered to observe the effect of data rate in terms of SINR performance. The convergence behavior of algorithms are compared as a function of the number of snapshots in the link and the fixed number of interferers, which provide the criteria to select the robust beamforming algorithms in fast fading channel environment
