说明： 4. 试说明卷积编解码的工作原理：
(1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。
(2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec:
(1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink.
(2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

说明： 在瑞利信道中，对于OFDM信号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(In Rayleigh channel, a specific guidance aided channel estimation method is designed for OFDM signal, and the simulation is carried out with Simulink to measure the BER performance of BPSK modulation. The relation curve between bit SNR and channel estimation mean square error is drawn, and the relation curve between bit SNR and bit error rate is drawn)
