线性调频信号和相位编码信号（七位巴克码）及他们的混合调制信号在matlab中的实现(The realization of the chirp signal and the phase-encoded signal (seven Barker code) and their hybrid modulation signal in matlab)

预留子载波法(TR)降低PAPR的matlab算法(Reserved subcarriers method (TR) matlab algorithm to reduce the PAPR)

说明：  仿真相干光通信系统，包含各种损伤和均衡算法(the model of coherent optical fiber channel)

说明：  STM32F4 SPI 4线驱动RA8875 彩屏方案(stm32f4 driver ra8875 TFT lcd display)

使用NMEA0183的gps服务程序原码(use of a GPS NMEA0183 service program source)

OFDM系统的LS和DFT信道估计的算法分析比较(LS and DFT OFDM system channel estimation algorithm analysis and comparison)

本程序主要使用matlab语言描述了信号调制方式是别的过程，当信噪比大于10时可以实现对所选信号调制方式的识别(signal processing matlab large than 10dB)

说明：  使用Simulink(或m语言)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(m语言方式)，不是调用Simulink(或m语言)的已有编码、译码函数。并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。(Simulink (or M language) is used to simulate convolutional coding, and Viterbi decoding method is used to decode, in which the coding and decoding are all written by themselves (M language mode), rather than calling the existing coding and decoding functions of Simulink (or M language). In the additive white Gaussian noise channel, the relationship curve between bit SNR and BER is drawn.)
