Abstract

The invention discloses a method for choosing sending the antenna in a multi-antenna input and output wireless system, which comprises the following steps: the receiving part dose channel estimation by the sent training sequence to obtain all the possible channel array H_e, and feedbacks the H_e to the sending part; it chooses K sending antennas from M sending antennas and first chooses I antennas, wherein I, M, K are natural number and K<M; if the rate of the corresponding condition number of the channel array of the chosen sending antenna and the candidate channel array condition is less than the pre-set threshold quantity alpha, it chooses the new chosen channel array as the candidate channel array and ascertains the chosen sending antenna as the sending antenna.

Description

technical field [0001] The present invention relates to a method and device for selecting a transmitting antenna in a multi-antenna input and output wireless communication system. In particular, it relates to a method and apparatus for selecting transmit antennas based on signal detection of a linear multiple-antenna input and output (MIMO) detector, thereby optimizing the detector bit error rate. Background technique [0002] Multiple Antenna Input and Output (MIMO) technology is a major breakthrough in the field of wireless mobile communication. MIMO technology refers to the use of multiple antennas for data transmission and reception. Studies have shown that the use of MIMO technology can increase the capacity of the channel, but also improve the reliability of the channel and reduce the bit error rate. The maximum capacity or upper capacity limit of a MIMO system increases linearly with the minimum number of antennas. Under the same conditions, the capacity of an ordi...
