BPSK

说明：  这是16QAM的仿真，带GUI界面，很好用的。(This is 16QAM simulation, with GUI interface, very useful.)

说明：  4098QAM编码在AWGN信道下误码率性能与Eb/N0（信噪比）的关系(The performance of 4096QAM at AWGN channel: BER~Eb/N0)

一系列包含串口、Modem、收发传真、终端仿真等方面的编程例子( A series of contains aspect the and so on string mouth, Modem, receiving and dispatching facsimile, terminal simulation programming example )

ieee802.15.4a信道模型.是2-10G部分，是SV模型(ieee802.15.4a channel model )

SIM300的封装，对于要用GSM搞硬件开发的人很(SIM300 package, for use GSM person engaged in the hardware development is)

OFDM 自适应算法能够根据信道的状况进行比特和功率的分配，能够有效的降低误码率.本程序综合了迭代注水算法，CHOW算法，FISHER算法，H-H算法，以及自己改进的迭代注水算法程序，并进行了对比，改进的算法在有效性与迭代注水算法基本相近，但复杂度和实际应用性都更强，值得参考。(OFDM adaptive algorithm make the bit and power allocation according to the status of the channel .It can effectively reduce the error rate.This program combines iterative algorithm, water injection CHOW algorithm, FISHER algorithm, the algorithm of H- H,as well as their improved iterative allocation algorithm procedures.And has carried on the contrast, the improved algorithm in effectiveness and iterative allocation algorithm basic similar, but the complexity and practical applications were stronger with worthy of reference.)

在MATLAB中用Goertzel算法（先用FFT算法，再用goertzel算法，）仿真DTMF的产生与检测的程序。应用于双音多频信号的产生与检测。(in Goertzel algorithm using MATLAB (first using FFT algorithm, reuse goertzel algorithm) simulation DTMF detection with the selection process. Used DTMF signal detection with the selection.)

说明：  简单实现基于各种加权分数傅里叶变换的混合载波系统(Simple implementation of hybrid carrier system based on various weighted fractional Fourier transform)
