A METHOD AND APPARATUS OF SPREAD SPACE-TIME BLOCK CODING

摘要

The present invention relates to a method and apparatus of spread space-time block coding. The method comprises the steps of space-time block coding input bits by a transmission side; converting the input bits into symbols and modulating said symbols; serial-parallel converting and channel interleaving the modulated symbols; transmitting the final symbols by at least two transmitting antennas; receiving the signal from said antennas by a receiving antenna at a receipt side; and processing the received signal. The present invention make any of block code with a rate of 1/N (such as different liner and non-liner block codes) be used in a system with N transmitting antennas. When using block codes with a long constraint length, we can obtain a greater coding gain than the conventional space-time block coding.
