WiMAX_Test_4
本程序是对IEEE 802.16e物理层和链路层的仿真。
使用matlab的simulink仿真工具，先运行data.m产生仿真数据，再运行WiMAX_Test_4.dll进行仿真。(This program is the physical and link layer simulation of IEEE 802.16e. The simulation uses the simulink tool of MATLAB. First,run data.m to generate data, and then run WiMAX_Test_4.dll.)

OFDM_Multipath_simulation
说明： OFDM是将高速串行数据分成成百上千路并行数据,并分别对不同的载频进行调制,这种并行传输体制大大扩展了符号的脉冲宽度,提高了抗多径衰落的性能。同时,在传统的频分复用方法中,各子载波之间的频谱互不重叠,频谱利用率较低。而采用OFDM技术,一个OFDM符号之内包括多个经过调制的子载波的合成信号,每个子载波在频谱上相互重叠,这些频谱在整个符号周期内满足正交性,因而在接受端可以保证无失真恢复,从而大大提高频谱利用率。(OFDM divides high-speed serial data into hundreds of parallel data channels and modulates different carrier frequency separately. This parallel transmission system greatly expands the pulse width of symbols and improves the performance of anti-multipath fading. At the same time, in the traditional method of Frequency Division multiplexing, the spectrum between the sub-carriers does not overlap each other, the spectrum utilization ratio is low. In the case of OFDM, an OFDM symbol consists of multiple modulated sub-carriers, each of which overlaps in the spectrum, which is orthogonal throughout the symbol period, thus, no distortion recovery can be ensured at the receiving end, thus greatly improving the spectrum utilization ratio.)

vipcodec
该系统实现了视频通信系统由通信模块库及使用从视频处理模块块基于MPEG - 1和DVB演示演示基于Simulink模块，它不从源编码，频道编码（RS编，卷积编码器）调制（QAM调制， OFDM）技术，信道及当时的整个过程相反，在接收端
然而，甚少是一个问题，那里的视频源编码器输出去到信道编码，当运行系统，则会出现错误，说的RS -编码器输入不正确，这种输入问题，我想，未来的视频输出
我不会令你对这个问题APRRECIATE＆应该是什么的RS编码器输入的大小帮助？
原因这是我的硕士论文设计之与我必须完成它正确
任何帮助，您奉献，都可以得益，因此，我感谢您关注..(Received OFDM signal transmitter, using the language toolbox matlab simulink technology)
