Abstract :
This paper presents a DSP-based implementation of an adaptive beamformer for the W-CDMA reverse link. A comparative study of LMS and RLS adaptive algorithms is shown, which leads to the implementation taking into account both performance results and computational load. Results for fixed-point DSP implementation and floating point simulations are presented.
