Abstract :
We present the architecture and VLSI implementation of a blind beamforming algorithm. An FIR filter based structure for eigenvector computations is proposed. We show that the structure can be optimally realized on a ring-processor based programmable multiprocessor IC. Chip characteristics and testing results for the IC are provided.
