Preamble-Based Channel Estimation for CP-OFDM and OFDMOQAM Systems A Comparative Study

说明：  TD-SCDMA物理层原理，了解物理层技术，了解信道编码的基本原理。(TD-SCDMA Physical Layer Principle)

实现信号处理中QAM调制、过信道、解调部分。其中QAM调制部分可改符号点数，M阶数，信道加高斯白噪声、时延、多径，调制解调均有星座图。通过本代码，可学习QAM调制解调，或者通信系统的知识。(To achieve QAM modulation, signal processing over channel, a demodulation section. QAM modulation section can be changed symbolic points M order channel additive white Gaussian noise, delay, multipath, the modem has constellation diagram. QAM modulation and demodulation, or communication system knowledge through this code, you can learn.)

用matlab实现简单的bpsk系统，熟悉bpsk系统的特性(Implementing BPSK with MATLAB)

这几章PPT讲述了C++面向对象编程思想的基本知识，最后用VC++举了一个例子(PPT these chapters on the basic knowledge of C ++ object-oriented programming ideas, and finally VC + cited an example)

说明：  opnet学习入门视频教程 这个对初学者很有用的(opnet Getting Started video tutorial to learn this very useful for beginners)

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)

这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性： 1. qpsk/16qam/64qam映射、解映射 2. OFDM调制解调（循环前缀，FFT等） 3. 非整数采样时刻多径时延的多径信道 4. Rayleigh或者Rician多径信道 5. 信道的连续时变（非block fading） 6. 线性插值信道估计 7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)

一个用MATLAB编写的，上变频为2.5GHz的OFDM仿真程序，很好用的程序，适合学习OFDM初学者(A MATLAB prepared, the frequency of 2.5 GHz OFDM simulation program, very good procedures, suitable for OFDM beginners to learn)
