基于平均匹配滤波的MSK多符号检测算法研究
Research on MSK multiple symbol detection algorithm based on average matched filtering
摘要
Abstract
Minimum shift keying(MSK)signal has the advantages of continuous phase,constant envelope and small band⁃width occupation,so it is widely used in modern wireless communication field. Proceeding from the memory characteristic of MSK signal,the general principle of MSK multiple symbol detection algorithm is studied,including coherent and non⁃coherent situations. The algorithm based on the thought of average matched filtering fulfills the judging output of current symbol by observing the received signals within the multipleple symbol interval. The simulation results show that,in comparison with the traditional symbol⁃by⁃symbol detection algorithm,the multiple symbol detection algorithm can obtain better detection performance because it takes the memory characteristic of the received signal into account. Considering the reliability and cost factor of the receiver in practical engineering,an appropriate demodulation algorithm is chosen to reach a trade⁃off between error rate performance and complexity.关键词
