本例用matlab语言实现了4QPSK的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。-Matlab language used in this case achieved 4QPSK codec and channel through awgn simulation. Monte Carlo simulation method, the BER performance, drawing curves. Algorithm can be used for research or courses.

正交频分复用（OFDM）系统是一种多载波系统，其利用并行处理技术允许在许多的同时传输数据的密切隔开，正交子载波。快速傅立叶逆变换（IFFT）和快速傅立叶变换（FFT）在传统的OFDM系统被用于复用信号一起和解码信号在分别的接收机。本文研究的性能离散傅立叶变换正交基频分复用（DFT-OFDM）。

wimax 标准中码率为1/2，码长为2304 的ldpc码的硬件实现编码及译码算法-wimax standard rate of 1/2, code length 2304 of the ldpc code encoding and decoding algorithm for hardware implementation

模拟16QAM调制解调过程（在AWGN信道条件下）-Simulation of 16QAM modulation and demodulation process (in AWGN channel conditions)

In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.-In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.

本代码用VERILOG HDL语言编写了SPI模块，通过用modelsim进行仿真，得到了正确的仿真结果，并将其下载到fpga开发板上进行试验，也得到了较好的效果。
