Patent ID: 7970048

Claim:
A transmitter comprising: M antennas; and a space-time coder, the space-time coder including: linear encoders configured to perform a respective full diversity linear encoding on each of P sets of K modulated symbols to generate P sets of T linearly encoded symbols; and a threader configured to assign each one of the P sets of T linearly encoded symbols to a corresponding one of threads of a M×T dimensional space-time code, the threads being allocated such that only one of the M antennas is used for transmission at each time interval of a given one of the threads and over time the M antennas are used substantially equally likely, wherein M>=2, 2<=P<=M, and T>=M, and wherein: each one of the linear encoding performed on each of the P sets of K modulated symbols is of full diversity and different from one another; and the M×T dimensional space-time code is of full diversity.
