    摘要: It is possible to realize a transmitter where a block of n symbols is encoded through an n×n matrix and transmitted over n antennas in n time intervals, only for n=2, 4, or 8. For all other numbers of antennas, the disclosed methodology permits the realization of full-rate rectangular designs, where the number of time intervals, p, is greater than n. In particular, the number of time intervals, p, is such that &rgr;(p)≧n, where &rgr;(p)=8c+2d, where c and d are such that p=b·24c+d, and b is an odd integer. Complex symbols can also be handled, but the rate for a design that allows use of any number of antennas is 0.5.

    摘要: A method and apparatus for increasing the data rate and providing antenna diversity using multiple transmit antennas is disclosed. A set of bits of a digital signal are used to generate a codeword. Codewords are provided according to a channel code. Delay elements may be provided in antenna output channels, or with suitable code construction delay may be omitted. n signals represent n symbols of a codeword are transmitted with n different transmit antennas. At the receiver MSLE or other decoding is used to decode the noisy received sequence. The parallel transmission and channel coding enables an increase the data rate over previous techniques, and recovery even under fading conditions. The channel coding may be concatenated with error correction codes under appropriate conditions.
