摘要：A transmitter, a receiver and a communication method enabling improvement ofthe data rate of an MIMO system. One signal xout of the three signals is combined with

the other two signals x, xrespectively to generate two combined signals x+x, x+x. Thecombined signals are transmitted through transmission antennas (). A signal separatingsection () of the receiver separates the received signals r, rinto two signals y, yby a signalseparation processing such as the ZF. An MLD processing section () generates MLDevaluation formulae using y, yand performs an MLD processing in which xis cancelledfrom y, yand evaluation formulae about x, xare generated, and a maximum likelihoodestimation is performed. As a result of the MLD processing, x, xare detected. In acanceling section () the detected x, xare canceled from y, y, and xis detected.
