FECOFDM

说明：  原始信号加载高斯白噪声和椒盐噪声后用维纳滤波器滤波(The original signal was loaded with White Gaussian noise and salt noise and then filtered by Wiener filter)

ofdm的编码过程，用evm和比特率进行对比(The encoding process of OFDM is compared with EVM and bit rate)

说明：  ofdm papr hammerstein python

MPSK QAM MASK MPSK信号载频估计matlab程序(matlab program of estimating Carrier Frequency of MPSK QAM MASK MPSK signal )

说明：  关于椭圆算法的，比较通俗易懂，供初学者用(Algorithm on the elliptical, more user-friendly for beginners with)

该函数能产生一个任意阶的范德蒙德数组,可以用在无线通信等诸多领域。(This matlab function will generate an arbitrary-way Vandermonde arry.)

Pin configuration for hy-640 GSM module

说明：  lbc_example：未编码的BPSK调制的性能（理论计算与仿真）、重复码硬判决的性能 lbc_example_SD： 未编码的BPSK调制的性能（理论计算）、重复码硬判决的性能、重复码软判决的性能 lbc_example_SD_EbNo：lbc_example_SD中的性能，并且进一步考虑了码率不同时，对于信道的SNR值进行归一化，以Eb/No = SNR/(2*R)为横坐标时的比较结果 lbc_example_Hamming_EbNo：汉明码，硬判决译码的性能(Lbc_example: Performance of uncoded BPSK modulation (theoretical calculation and simulation), performance of duplicate code hard decision Lbc_example_SD: Performance of uncoded BPSK modulation (theoretical calculation), performance of hard decision of duplicate code, performance of soft decision of duplicate code The performance of lbc_example_SD_EbNo: lbc_example_SD is considered, and the SNR value of channel is normalized when the bit rate is different. The comparison results are obtained when Eb/No = SNR/(2*R) is the abscissa coordinate. Lbc_example_Hamming_EbNo: Hamming Code, Performance of Hard Decision Decoding)

说明：  bpsk和4pam调制系统误码率和误符号率仿真，以及与理论值比较。(Simulation of BER and BER in 4pam modulation system)
