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.)

OFDM_Channel-estimation
OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道,是每个子信道的想干带宽,从而实现平稳衰落。搭建了完整的OFDM信道链路系统,运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计),并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。(OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is decomposed into a number of parallel narrow subchannels, each subchannel wanted bandwidth, in order to achieve a smooth fading. Build a complete OFDM channel link system, the use of three kinds of different channel estimated method (LS channel estimated, to the DFT letter Tao estimates, Improved-the DFT letter Road estimated), and AWGN ideal letter Road and fading channel bit error situation conducted a simulation and comparison .)
