摘要
Devices and methods for decoding a symbol transmitted over a millimeter wave (mmWave) channel. Receiving a test symbol transmitted over the mmWave channel. Estimating channel state information (CSI) of the mmWave channel using a block sparse signal recovery on the test symbol, according to a multi-dimensional spreading model with statistics on multi-dimensional paths. The multi-dimensional spreading model with statistics on multi-dimensional paths include an angle of departure (AoD), angle of arrival (AoA), and a path spread for the AoD and a path spread for the AoA, propagating in the mmWave channel. Receiving a symbol over the mmWave channel, and decoding the symbol using the CSI, wherein steps of the method are performed by a processor of a receiver.
