为了提高移动通信系统中数据传输的有效性能,降低GMSK调制系统的误码率. 首先对GMSK调制系统进行分析,得到不同BT值GMSK调制的移动通信系统误码率和带宽的关系.通过引入具有纠错性能的编码技术,降低信息传输的误码率,提高系统的有效性. 本文给出了引入编码技术的GMSK调制系统的仿真模型,仿真结果表明,在相同的信噪比下,系统的误码率降低了1～2dB.(This paper mainly intends to improve the performance of the communication system and decrease the error bit rate of the information. First , the GMSKmodulation system was analyzed , and the relation of the BER and bandwidth in the different BT value was obtained. By introducing the encoding technology , the error bit rate of the information was lowered so that the performance of systemwas improved. This paper presents a simulated model . The results show that the BER of the system in the same SNR can lower 1 to 2 dB.)

一道matlab例题，适合初学者学习，内容仅供参考，如有更好的方法请推荐。(A matlab example, suitable for beginners to learn, is only for reference, if you recommend a better way.)

qpsk源程序，有gui界面，很不错，包含误码率分析，频谱、功率谱分析，还有星座图(qpsk source, a gui interface, very good, including bit error rate analysis, spectrum, power spectrum analysis, as well as constellation)

一般的esprit算法计算复杂度高，在计算子空间是算法比较烦，改一些矩阵算法可以减少其复杂度。(Esprit general algorithm of high computational complexity in the calculation of subspace algorithms trouble is, some matrix algorithm can be changed to reduce its complexity.)
