Efficient algorithm for decoding layered space-time codes

A decoding algorithm for layered space time (LST) codes was proposed. The algorithm based on the Gram-Schmidt decomposition required less computational effort. Space-time codes (STC) were introduced to take advantage of multiple antennas and to use space as a second dimension of coding. Successive interference cancellation was used to decode distinct layers employing a nulling vector computed on the basis of the Moore-Penrose pseudo inverse.
