Dalam makalah ini, pengesanan pembezaan berbilang simbol (MSDD) digunakan pada skema pengekodan kekerapan ruang-masa-masa (DUSTFC) unitari ke atas saluran berbilang input berbilang input (MIMO) pudar frekuensi terpilih. Motivasi menggunakan MSDD adalah untuk mengimbangi kehilangan prestasi pengesanan pembezaan konvensional (pemerhatian dua simbol) berbanding dengan pengesanan koheren, dengan memanjangkan selang pemerhatian dan mempertimbangkan autokorelasi yang pudar. Memandangkan pengekodan pembezaan DUSTFC boleh dilakukan dalam domain masa atau frekuensi, kedua-dua domain masa dan domain frekuensi MSDD disiasat. Selepas mengira autokorelasi pudar domain frekuensi, metrik keputusan MSDD mempertimbangkan autokorelasi pudar yang sesuai diterbitkan masing-masing dalam domain masa dan frekuensi. Prestasi kadar ralat bit (BER) bagi kedua-dua jenis MSDD dianalisis dengan simulasi komputer. Keputusan simulasi menunjukkan bahawa peningkatan prestasi yang besar boleh diperolehi dengan menggunakan MSDD dalam kedua-dua kes, dan keuntungan kepelbagaian penghantaran juga boleh dipertingkatkan dengan menggunakan MSDD. Supaya terbukti bahawa kelebihan penuh menghantar kepelbagaian dengan DUSTFC boleh diambil dengan menggunakan 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.
