Abstract:
1. A method of a multiple input multiple output communication system, comprising: receiving, by N receive antennas at a receiver, N being an integer greater than 1, data, which have been coded through a double-space time transmit diversity (D-STTD) scheme and transmitted through M transmit antennas from a transmitter, M being an integer greater than 1; detecting, at the receiver, the received data through an ordered successive interference cancellation-minimum mean-square error (OSIC-MMSE) scheme, and parallelizing M received data; and decoding, at the receiver, the received data, which has been parallelized, through the modulation and coding schemes that has been applied to the received data, wherein the detecting the received data through the OSIC-MMSE scheme and parallelizing the M received data comprises: calculating error probability for each of the M transmit antennas; setting a detection order of the received data in sequence of the transmit antennas representing lowest error probability to the transmit antennas representing highest error probability; detecting the received data from each transmit antenna according to the detection order; and detecting the received data having a next detection order from the received data except for the received data that has been detected.
