OFDM信道估计仿真

WCDMA无线接口物理层，经典典WCDMA无线接口物理层，经典 (WCDMA radio interface physical layer, the classic typical WCDMA radio interface physical layer, the classic)

说明：  卫星信道信道估计的matlab仿真程序，对不同的插值算法给出比较输出并画出误码率-信噪比曲线(Satellite channel channel estimation matlab simulation program, different interpolation algorithms and draw the comparison output is given BER- SNR curve)

说明：  伪随机LED灯，实现八位LED灯的随机闪烁以及其它的控制。(Pseudo-random LED lamp)

基于ARM的嵌入式程序设计.rar,对arm的学习会有很大的帮助。(ARM-based embedded programming. Rar, on the arm of the study will be of great help.)

说明：  详解莱斯信道与瑞利衰落信道，并将其对比，画出图形，便于理解(Rician channel and Rayleigh fading channel are explained in detail and compared Draw a figure, easy to understand)

标准MODBUS规约文档。Modbus 协议是应用于电子控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通信。它已经成为一通用工业标准。(Standard MODBUS Statute of the document. Modbus protocol is applied to an electronic controller on the lingua franca. With this agreement, the controller between the controller via the network (such as Ethernet) and other devices can communicate. It has become a common industry standard.)

这是自由空间光通信实现OOK、PPM、DPPM调制解调并计算在高斯信道中的误码率的Matlab程序。(This is a free-space optical communications to achieve OOK, PPM, DPPM modulation and demodulation in the Gaussian channel and calculate the bit error rate in Matlab.)

本程序是对低密度奇偶校验码的校验矩阵的源程序，相信会对研究ldpc码的人会很有帮助的(This procedure is a low-density parity check matrix of code source, I believe that research on LDPC codes will be very useful)

GMSK modulation code.

说明：  生成2KHz和8KHz的混合信号,使该信号通过上述滤波器,观察滤波前后的波形变化和频谱分布情况, 在改信号中加入高斯白噪声,(The mixed signal of 2KHz and 8KHz is generated so that the signal passes the above filter, the waveform change and spectrum distribution before and after filtering are observed, and Gao Si white noise is added to the modified signal.)
