Neste artigo, a detecção diferencial de múltiplos símbolos (MSDD) é aplicada ao esquema de codificação diferencial unitária de espaço-tempo-frequência (DUSTFC) sobre canais MIMO (múltiplas entradas e múltiplas saídas) com desvanecimento seletivo de frequência. A motivação da aplicação do MSDD é compensar a perda de desempenho da detecção diferencial convencional (observação de dois símbolos) em comparação com a detecção coerente, estendendo o intervalo de observação e considerando o desbotamento das autocorrelações. Como a codificação diferencial do DUSTFC pode ser realizada no domínio do tempo ou da frequência, tanto o MSDD no domínio do tempo quanto no domínio da frequência são investigados. Depois de calcular a autocorrelação de desvanecimento no domínio da frequência, as métricas de decisão do MSDD considerando as autocorrelações de desvanecimento apropriadas são derivadas no domínio do tempo e da frequência, respectivamente. O desempenho da taxa de erro de bit (BER) dos dois tipos de MSDD é analisado por simulações de computador. Os resultados da simulação demonstram que um ganho considerável de desempenho pode ser obtido com a aplicação do MSDD em ambos os casos, e o ganho de diversidade de transmissão também pode ser melhorado com a aplicação do MSDD. Para que fique provado que todas as vantagens da diversidade de transmissão com DUSTFC podem ser obtidas aplicando-se o MSDD.

Abstract: In this paper, multiple-symbol differential detection (MSDD) is applied to the differential unitary space-time-frequency coding (DUSTFC) scheme over frequency selective fading multiple-input multiple-output (MIMO) channels. The motivation of applying MSDD is to compensate for the performance loss of conventional (two-symbol observation) differential detection comparing with coherent detection, by extending the observation interval and considering the fading autocorrelations. Since the differential coding of DUSTFC can be performed in time or frequency domain, both the time-domain and frequency-domain MSDD are investigated. After calculating the frequency-domain fading autocorrelation, the decision metrics of MSDD considering appropriate fading autocorrelations are derived in time and frequency domain respectively. Bit error rate (BER) performances of the two kinds of MSDD are analyzed by computer simulations. Simulation results demonstrate that a considerable performance gain can be got by applying MSDD in both cases, and the transmit diversity gain can also be enhanced by applying MSDD. So that it is proved that full advantage of transmit diversity with DUSTFC can be taken by applying MSDD.
