Abstract:
1. A method for transmitting encoded signals over a communication channel of a communication system, the method comprising: receiving a plurality of input signals; generating a plurality of output signals in response to the plurality of the input signals; and outputting a code word according to the plurality of output signals, wherein the code word has a predetermined algebraic construction for space-frequency coding based upon the communication channel being characterized as a frequency selective block fading channel, the construction of the code word in the outputting step defining a matrix equation, wherein the polynomials, X(D) and Y(D), correspond to the plurality of input signals and the plurality of output signals, respectively, L t representing the number of transmit antennas, L ISI representing the number of fading blocks associated with the communication channel, k representing number of input sequences.
