Abstract:
1. A self-adapting transmission scheme of a channel environment in a multi-antenna wireless transmission system, comprising: obtaining a statistical channel information at a receiving end using a result of a channel estimation, the statistical channel information comprising a Tx and Rx-correlated channel matrix, a spatial power flooding matrix, a number of distinguishable channel streams, and an online channel capacity; then, quantizing and encoding the obtained statistical channel information to get feedback bit information, and transmitting the feedback bit information to a transmitting end through a feedback channel; wherein the transmitting end calculates a plurality of link self-adapting control parameters from the statistical channel information, the statistical channel information further being used for controlling coding modulation and sending a pre-code; wherein the transmitting end obtains a digital base band transmission signal using a characteristic mode transmission method and a random virtual space selection transmission method, and the receiving end carries out self-adapting receiving using the same parameters; and the Tx and Rx-correlated channel matrix is determined by: where R
