Viterbi_Algorithm

LDPC coded OFDM system for power line communication in the presence of both AWGN and Impulsive noise..

说明：  The reference communication system for Orthogonal Time Frequency Space modulation

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)

本程序代码包含了 SC SCL BP SCAN和SSC译码算法，以及各种编码算法GA，BA....*** 编程语言风格为C++，研究polar的和我一样渣渣的研一萌新点进来have a look 感谢大佬pan jianpeng ，感谢共享源码(This program code includes SC SCL BP SCAN and SCC decoding algorithm, as well as various coding algorithms GA, BA... *** Programming language style is C++, research polar and slag like me have a look Thank you pan jianpeng, thank you for sharing the source code)

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)
