Robust Hybrid Beamforming With Quantized Deep Neural Networks
2019 IEEE 29th International Workshop on Machine Learning for Signal Processing (MLSP), 2019 Hybrid beamforming is integral to massive multiple-input multiple-output (MIMO) communications in reducing the training overhead and hardware cost associated with large antenna arrays. Prior works have employed optimization and greedy search to jointly estimate the precoder and combiner weights.
