METHOD OF SPACE BLOCK CODING SIGNAL TRANSMISSION AND RECEIVE WITH INTERACTIVE MULTIUSER DETECTION, AND APARATUS USING THE SAME

摘要

An apparatus and a method for transmitting and receiving a space block coding signal are provided to obtain an efficient transmission diversity gain by detecting the multiuser interference by the multiuser detection. A multiuser interference offsetting unit(207) offsets the multiuser interference of the reception signal by using a recovery signal for the reception signal. A linear coupling unit(209) linearly couples a first signal and a second signal successively transmitted from two different transmission antennas or more among the received signal offsetting the multi user interference. An equalizer(213) performs the frequency domain equalization by applying two different equalization coefficients to the first and second signals which are linearly coupled.
