CODIFICADOR ESPAÇO-TEMPORAL DE BLOCO QUASE ORTOGONAL, DECODIFICADOR E MÉTODOS DE CODIFICAÇÃO ESPAÇO-TEMPORAL E DECODIFICAÇÃO DE SINAIS MULTIPLEXADOS DE DIVISÃO DE FREQÜENCIA ORTOGONAL EM UM SISTEMA DE MÚLTIPLA ENTRADA E MÚLTIPLA SAÍDA.

摘要

Embodiments of quasi-orthogonal space-time encoder, decoder and method for space-time encoding and decoding orthogonal frequency division multiplexed (OFDM) signals in a multiple-input multiple-output (MDMO) system are generally described herein. Other embodiments may be described and claimed. In some embodiments, a method of decoding received multicarrier signals comprises deriving objective functions from a received signal matrix, minimizing the objective functions to generate decoded hard bits, and solving a set of linear equations of the objective functions to generate decoded soft bits.
