用与电话和电脑的串行通讯，用的是VB写的一些介绍和实例(Used with the telephone and computer serial communications, using VB to write the introduction and examples of some)

说明：  本文介绍了如何使用264芯片，并对可编程增益可调的滤波器max264做了具体说明.(for how to use max264)

这是一个将语音信号通过DPCM编码传输的仿真测试程序，内有详细注释，希望对大家有用。(This is a voice signal transmission through the DPCM code simulation testing procedures, with detailed notes, We hope that the right useful.)

The "feature" parameter in the isSupported(feature,version)" method is the name of the feature and the version is the version number of the feature to test.

说明：  各种polar编译码函数，包括SC译码，BP译码，SCL译码以及循环检测编码(Various polar encoding and decoding functions, including SC decoding, BP decoding, SCL decoding and cyclic detection coding)

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：  实现了64qam，16qam和QPSK的误码率仿真(The bit error rate simulation of 64qam, 16QAM and QPSK is realized.)
