Evans, "Resolution-Adaptive Hybrid MIMO Architectures for Millimeter Wave Communications", MATLAB code to accompany a paper of the same title in the IEEE Transactions on Signal Processing, vol. 65, no. 23, pp. 6201-6216, Dec. 2017, DOI 10.1109/TSP.2017.2745440. Software release is version 1.0 (Nov. 15, 2018).

Signal Compression for Basestations

  1. Jinseok Choi and Brian L. Evans, "Space-Time Baseband LTE Compression Software", copyright © 2016 by The University of Texas. This MATLAB release implements algorithms to compress uplink baseband cellular LTE signals received by an antenna array. Software release accompanies the paper "Space-Time Fronthaul Compression of Complex Baseband Uplink LTE Signals" in the 2016 IEEE International Conference on Communications. Version 1.0 (April 4, 2016).
  2. Karl F. Nieman, Marcel Nassar, Jing Lin and Brian L. Evans, "Approximate Message Passing (AMP) Receiver". Release contains an AMP algorithm for decoding complex-valued orthogonal frequency division multiplexing (OFDM) signals. The algorithm estimates the impulsive noise observed on the null tones at the receiver to subtract out an estimate of the impulsive noise in the current OFDM frame. The AMP algorithm models the impulsive noise using a two-term Gaussian mixture model. Version 1.0 (June 5, 2013) contains two components:
