Abstract: The present invention provide a space time block codes (STBC) scheme, where a received signal is filtered by using a minimum mean square error (MMSE) filter, and where channel symbols are individually decoded and converted into bit information, so that an mean square error (MSE) can be minimized by using a linear superposition form applicable to the non quasi-static channel environment as well as a quasi-static channel environment. The present invention provides an STBC scheme using a MMSE filter obtained in a real linear representation method, so that transmitted data can be recovered without loss thereof even in a case where a speed of a mobile station is high.

Abstract: A receiver for a hybrid space time block codes (STBC) scheme using a nonlinear decision feedback (DFB) filter instead of a conventional linear filter which are used in the hybrid STBC scheme, that is, a combination of a spatial division multiplexing (SDM) scheme and a STBC scheme. In the receiver used for the STBC scheme, a previous-stage remaining signal is detected by using a well-known BLAST algorithm, and inter-symbol interference (ISI) is minimized by applying the previous-stage remaining signal to a current-stage signal, providing improved performance. The receiver used for the STBC scheme can be applied to a time varying channel fading environment as well as a quasi-static channel environment. According to the hybrid STBC scheme, a gain of about 3 dB can be obtained in channel environments having a frame error rate (FER) frequency efficiency of 2 and 3 Bps/Hz in the same condition by using a simulation.

Abstract: An apparatus and a method for determining an optimum integer perturbation vector of a low complexity in a multiple antenna system include a transmitter that transmits data using an optimum integer perturbation vector of a low complexity in a multiple antenna system includes a module pre-processor, a shift pre-processor, and a precoder. The modulo pre-processor adds an integer perturbation vector to a transmission signal vector. The shift pre-processor phase-shifts a pseudo inverse matrix of a channel matrix using a phase angle. The precoder precodes a transmission signal vector perturbed by the integer perturbation vector using the phase-shifted pseudo inverse matrix of the channel matrix.
