System and method for mmWave channel estimation

摘要

A method for decoding a symbol transmitted over a millimeter wave (mmWave) channel estimates channel state information (CSI) of the mmWave channel using a Bayesian inference on a test symbol according to a probabilistic model of the mmWave channel including statistics on paths and spread of mmWaves propagating in the mmWave channel and decodes a symbol received over the mmWave channel using the CSI.

1. A method for decoding a symbol transmitted over a millimeter wave (mmWave) channel from a transmitter to a receiver, comprising:
receiving, using a set of antennas of the receiver, symbols transmitted over the mmWave channel from the transmitter to the receiver; converting, using a front end of the receiver, the symbols into at least a test symbol and a data symbol; estimating, using a probabilistic channel estimator of the receiver, channel state information (CSI) of the mmWave channel using a Bayesian inference on the test symbol according to a probabilistic model of the mmWave channel including statistics on paths and spread of mmWaves propagating in the mmWave channel, wherein the probabilistic channel estimator is implemented using a processor executing software instructions estimating the CSI using the Bayesian inference; and decoding, using a decoder of the receiver, the data symbol using the CSI, wherein steps of the method are performed by the processor of the receiver.
