AWGN信道模型下的模拟调制解调matlab实现

说明：  产生复高斯的白噪声,这和matlab 自带的不一样，容易理解，但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)

进行基于C语言的BPSK通信心痛调制解调的仿真(Simulation of modulation and demodulation of heart pain in BPSK communication based on C language)

说明：  7. 单径瑞利信道中的两发一收STBC： (1) 分析误码率的理论性能，画出比特信噪比与误码率的关系曲线。 (2) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。(7. Two outgoing and one outgoing STBC in single-path Rayleigh channel: (1) analyze the theoretical performance of bit error rate and draw the curve of the relationship between bit SNR and bit error rate. (2) please design a specific navigation-assisted channel estimation method, Simulink simulation, measurement of BPSK modulation error rate performance.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn.)

通过2FSK通信系统综合设计实验，加强对2FSK调制器与解调器的通信技术电路理解，学会查寻资料、方案比较，以及设计计算环节。学会对所学基本理论知识的综合运用；掌握使用Multisim软件的操作方法(Through the comprehensive design experiment of 2FSK communication system, we need to enhance the understanding of the communication technology of 2FSK modulator and demodulator, learn to search for data, compare schemes, and design calculation links. Learn the comprehensive application of basic theoretical knowledge and master the operation method of using Multisim software)

说明：  多子带自适应算法，能够有较好的鲁棒性以及稳态特性。(The multi-subband adaptive algorithm has better robustness and steady-state characteristics.)

脉冲压缩的匹配滤波。目标距离分别为10米，30米和100米，对于未压缩的脉冲，三个回波信号混叠在一起，不能分辨，而经过脉冲压缩的脉冲信号则可通过匹配滤波收到3个回波信号(Matched filtering for pulse compression.Target distances are 10 metres, 30 metres and 100 metres, respectively. For uncompressed pulses,The three echo signals are overlapped and can not be distinguished. While pulse compression can distinguish three echo signals after matched filtering)
