<p>PURPOSE: A transmission and reception method based on vector perturbation in a multiuser multiple antenna system is provided to promote a BER(Bit Error Rate) performance by simultaneously considering of interference, a fading channel, and noise. CONSTITUTION: A transmission apparatus executes vector perturbation for a transmission target user symbol(S210). The transmission apparatus outputs the data symbol by adding the user symbol and a perturbation symbol(S220). The transmission apparatus creates the second data symbol by multiplying a first data symbol by the set first pre-coding matrix(S230). The transmission apparatus creates a third data symbol by multiplying the second data symbol by the set second pre-coding matrix(S240). The transmission apparatus transmits the created third data symbol(S250). [Reference numerals] (AA) Start; (BB) End; (S210) Pertubation symbol is created by executing a vector pertubation for a user symbol; (S220) A first data symbol is outputted by summing a user symbol and a pertubation symbol; (S230) A second data symbol is created by multiplying a first data symbol by the set first pre-coding matrix; (S240) A third data symbol is created by multiplying a second data symbol by the set second pre-coding matrix; (S250) A third data symbol is transmitted through a plurality of transmission antennas</p> |
