A receiver for use in MIMO system

摘要

A receiver is provided which is operable to receive a multiple element signal resultant from a MIMO transmission. The receiver includes decoding means for identifying symbols, from a predetermined set of such symbols, carried in the signal. The decoding means is operable to estimate the corresponding bits according to a pre-defined mapping of symbols to bits along with associated likelihood information representing the likelihood of an identified bit being such a bit. The decoding means is operable in two functional stages. A first decoding stage searches exhaustively across a set of possible symbols for the most likely candidate symbol, while a second stage takes account of an orthogonal transmission of information on two transmit antennas and decodes this information accordingly. The second stage is operable to detect remaining bits of data.
