Abstract
We consider compressive sensing (CS)-based beam alignment for time-varying millimeter wave (mmWave) MIMO channels. We propose a symbol-based beam switching (SBBS) approach with channel-probing beams being switched every OFDM symbol. We use the SBBS to measure second order statistics of the channel, which are used for sparse recovery. We formulate the problem for a wideband channel model with pulse shaping. We consider low signal-to-noise ratios (SNRs) typical of mmWave channels and different fading rates in our simulations. Simulations show that our proposed SBBS approach outperforms existing approaches designed for longer beam-switching times.
