摘要

近幾年來無線系統傳輸的分集已經廣泛的被研究，多階層空時區段碼的技術已是根據編碼増益距離的討論，再結合多階層信號集合分割的概念及空時區段碼。我們在多階層空時區段碼的系統加入里德所羅門碼作為聯結外部碼。模擬結果顯示我們所提出聯結碼系統，可以達到很好的位元錯誤率與低解碼複雜度。

Over past several years, transmit diversity has been studied extensively to provide error performance for wireless systems. A novel technique for constructing multilevel space-time code is proposed. For a given orthogonal space-time block code, several component codes are combined in conjunction with set partitioning of the multidimensional signal constellation according to the coding gain distance criterion. Then, the associated scheme is further concatenated with an outer Reed-Solomon code. Simulation results show that the concatenated scheme can achieve excellent error performance with low decoding complexity.
