功能还算完善，可能最后调试有小的问题，但是功能模块基本实现(just do it)

QAM系统的全数字设计，学位论文，较长较细致，值得参考，不多说，免费下(QAM system, all-digital design, dissertations, longer than the detail, it is also useful, not more than that under free)

A GUI software I made to calculate the carrier-to-noise-density ratio of a earth-satellite link.

I would like this program in simulink matlab. Please help me.

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.)
