METHOD AND SYSTEM FOR MULTIPLE INPUT AND MULTIPLE OUTPUT CHANNEL ESTIMATION

摘要

The invention relates to a method and system for multiple input and multiple output channel estimation, which can be used to generate and correlate sets of complementary sequences of length N, having a number of elements K greater than or equal to two. According to the invention, a block is used to generate sequences and to convolve same with an input signal, after which they are sent directly, or modulated, to the transmission channel. Once they have been received, and optionally demodulated, they pass through a correlator filter such as to obtain the input signal convolved by the channel, having a noise level reduced by factor KN.
