Recentemente, foram propostos novos códigos de bloco de espaço-tempo quase ortogonais (QSTBCs) de taxa total de diversidade total com escalonamento de potência e decodificação de máxima verossimilhança (ML) de símbolo duplo. Especificamente, os códigos podem alcançar diversidade total através da combinação linear de dois códigos de bloco de espaço-tempo ortogonais (OSTBCs) com escala de potência adequada. Nesta carta, derivamos expressões para informação mútua e relação sinal-ruído (SNR) de pós-processamento para um sistema com quatro antenas de transmissão. Explorando essas fórmulas, propomos três métodos de agrupamento de antenas de transmissão (TAG) para um sistema em malha fechada com informações de feedback de baixa taxa. Os métodos TAG permitem fornecer um excelente desempenho de taxa de erro mesmo com detecção de força zero (ZF) de baixa complexidade, especialmente em canais de desvanecimento espacialmente correlacionados.

Abstract: Recently, novel full-diversity full-rate quasi-orthogonal space-time block codes (QSTBCs) with power scaling and double-symbol maximum likelihood (ML) decoding was proposed. Specifically, the codes can achieve full-diversity through linearly combining two adequately power scaled orthogonal space-time block codes (OSTBCs). In this letter, we derive expressions for mutual information and post-processing signal-to-noise ratio (SNR) for a system with four transmit antennas. By exploiting these formulas, we propose three transmit antenna grouping (TAG) methods for a closed-loop system with low-rate feedback information. The TAG methods make it possible to provide an excellent error-rate performance even with a low-complexity zero-forcing (ZF) detection, especially in spatially correlated fading channels.
