TRANSMISSION WEIGHT DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication method for achieving linear precoding which can provide excellent BER (Bit Error Rate) characteristics with reduced computational complexity in comparison with the prior arts.

SOLUTION: The wireless communication method for receiving signals transmitted by a plurality of antennas via a single antenna includes: correcting a transmission weight of linear precoding through phase rotation of a dominant interference wave in the case where the transmission weight is applied to transmission; and enhancing BER characteristics according to a standard for maximizing a distance between signal points. According to the method, a single or more leak allowed terminal stations are set when calculating a transmission weight to be set first, a transmission weight of a SINR (Signal to Interference Noise Ratio) criterion for minimizing an average square error is calculated while taking into account a present terminal station itself and all the terminal stations other than the leak allowed terminal stations, and a transmission weight corresponding to the present terminal station is used as a transmission weight of the present terminal station.
