项目摘要

(4,12) Circular-Signal-Set constellation has been proposed for 16 APSK and its optimum ring ratio has been given by maximizing minimum Euclidean distance between mapped signal points in high channel SNR. But in order to get the best performance in low SNR, the optimum ring ratio should be calculated by using its symbol error rate (SER). Thus, we analyze its symbol error rates theoretically for several detection schemes, which are the ideal coherent detection, the envelope amplitude/coherent phase detection, and the envelope amplitude/differential phase detection.Multiple-symbol differential detection (MSDD) based on the maximum likelihood (ML) criterion is proposed for APSK and its decision metric is given through the likelihood function, which is derived with no assumption. The SER performance of 16 APSK with this detection scheme shows better than that by using the approximated metric given in the past literature. To reduce the complexity and the computational efforts in the receiver … More , the (M, L)-algorithm is applied to tree path search in this detection scheme. As the result, the sequence length of received signals to be estimated can be chosen quite large under a practicable receiver structure, and we confirm that the SER performance shows almost the same as that of the ideal coherent detection with the optimum ring ratio.Lastly we propose a novel adaptive MSDD scheme that has excellent performance over frequency selective fading (FSF) channels. The adaptive MSDD scheme consists of an adaptive non-coherent least mean square channel estimator that can accomplish channel estimation without any decision delay and the MSDD. Because of the application of the adaptive channel estimator and the M-algorithm, this adaptive MSDD make it possible that channel estimation is accomplished for every symbol along M surviving paths without any decision delay. And the SER performance of this adaptive MSDD is not affected by phase fluctuation introduced by a channel because the MSDD and the non-coherent channel estimator are applied. The adaptive MSDD scheme is applied to typical constellation of 16 APSK, the (4,12) QAM and the star QAM. The excellent tracking performance of this adaptive MSDD scheme over FSF channels is confirmed by computer simulations. Less
(4,12)提出了一种适用于16 APSK的环形信号集星座图,并通过最大化高信道信噪比下映射信号点之间的最小欧氏距离给出了其最佳环比。但为了在低信噪比下获得最佳性能,需要利用其误符号率(SER)来计算最佳环比。为此,本文从理论上分析了理想相干检测、包络幅度/相干相位检测、包络幅度/差分相位检测等几种检测方案的误符号率,提出了基于最大似然准则的APSK多符号差分检测(MSDD),并通过无假设推导出的似然函数给出了MSDD的判决度量。16 APSK信号的误码率性能表明,该检测方案优于以往文献中给出的近似度量。为了降低接收机中的复杂度和计算工作量, ...更多信息 该检测方案将(M,L)-算法应用于树路径搜索。结果表明,在实际的接收机结构下,待估计接收信号的序列长度可以选择得很大,在最佳振铃比下,其误码率性能与理想相干检测的误码率性能基本相同。最后,提出了一种新的自适应MSDD方案,该方案在频率选择性衰落信道下具有良好的性能。自适应MSDD方案包括一个自适应非相干最小均方信道估计器,它可以完成信道估计没有任何决策延迟和MSDD。由于自适应信道估计器和M算法的应用,该自适应MSDD使得对沿着M条存活路径上的每个符号都进行信道估计而没有任何判决延迟成为可能。由于采用了MSDD和非相干信道估计器,该自适应MSDD的误码率性能不受信道引入的相位波动的影响。将自适应MSDD方案应用于16 APSK、(4,12)QAM和星星QAM的典型星座。计算机仿真结果证实了该自适应MSDD方案在FSF信道下具有良好的跟踪性能。少
