使用matlab仿真hitran，用以计算气体吸收系数计算(Use matlab simulation hitran, to calculate gas absorption coefficient calculation)

说明：  matlab源码编写的QPSK调制与解调程序，含载波及采样频率(matlab source code written in QPSK modulation and demodulation process, including the carrier and sampling frequency)

说明：  MATLAB环境下，一维小波分解并提取细节系数和近似系数，再加小波包分解信号(MATLAB environment, the one-dimensional wavelet decomposition and extract detail coefficients and approximation coefficients of wavelet packet decomposition of signal plus)

说明：  利用 matlab 分别基于 ACF 和 W-AMDF 求基音频率，程序均调试通过。其中的 word 文档为下载资源，供大家参考对比(compute fundamental frequency of speech signal base on ACF and W-AMDF respectively, while the download word document for your reference.)

用蒙特卡洛法模拟编写的计算粒子的多次散射和单次散射的比较(Comparison of multiple scattering method using Monte Carlo simulation calculations prepared particles and single-scattering)

Space-Time Codes and MIMO Systems书籍及书籍内matlab代码程序，程序非常好，对研究MIMO系统的研究人员很有用(Space-Time Codes and MIMO Systems book and matlab code)

地震数据SEGY的读写，使用matlab，简单易用。(seismic data SEGY s reading and writing)

ofdm 基带传输 信道编码译码 卷积码译码(OFDM baseband transmission channel coding and decoding the convolutional code decoder)

比较采用干扰消除和无干扰消除的V-BLAST系统误帧率与SNR的关系曲线。系统参数：收发天线个数M=4，N=6；设定发送信号总功率P=1；设定每一帧中的符号数Nframe=100；调制方式为16QAM；信道为不相关瑞利衰落信道。(Was used to compare the interference canceller and V-BLAST system without interference cancellation, the frame error rate and SNR curve. System parameters: the number of transmit and receive antennas M = 4, N = 6 set to send the signal power P = 1 set the number of symbols in each frame Nframe = 100 modulation for 16QAM channel is not related to Rayleigh fading channel.)
