Beamspace processing is an emerging paradigm to reduce hardware complexity in all-digital millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) basestations. This approach exploits sparsity of mmWave channels but requires spatial dis

We propose SParsity-ADaptive Equalization (SPADE), a novel approach to reduce the effective number of multiplications in sparse inner products by adaptively skipping multiplications that have little to no effect on the result. We apply SPADE to beams

Power consumption is one of the most significant technical barriers for practical millimeter wave (mmWave) communication devices for mobile applications. Communication in the higher mmWave bands above 100 GHz will face even greater challenges. This p
