用simlink开发的space-time coding仿真模型,仿真的精度与效率有不小的提高(with simlink development of the space-time coding model, Simulation accuracy and efficiency are not a small increase)

This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. (This simulation script set allows for an OF DM transmission to be simulated.

通信系统设计，数字带通传输系统仿真Matlab代码 1. 比较BPSK与QPSK两种调制方式的误码率和误比特率性能（注意QPSK的误码率不同于误比特率），横坐标为SNR，并与理论曲线比较，分析解释仿真图。 2. 要求使用Matlab/C语言/Matlab-simulink中的任一种工具实现。 3. 代码中每个模块都要有详细注释说明。 (Communications systems design, digital bandpass transmission system simulation Matlab code 1. Comparison of BER QPSK and BPSK modulation methods and bit error rate performance (note QPSK error rate is different bit error rate), the horizontal axis is SNR, and compared with the theoretical curve, analysis and interpretation of simulation map. 2. requires the use of Matlab/C language/Matlab-simulink any one tool to achieve. 3. The code of each module must have a detailed explanatory notes.)

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)
