高斯脉冲的峰值频率。把各阶导函数的ESD作为α的函数，确定其峰值频率的数值。-Gaussian pulse of peak frequency. The derivative function of the ESD as a function of α, determine the frequency of its peak value.

这个是802.16a的三径莱斯信道模型的Matlab源代码，可直接使用。

CDMA中的扩频解扩，用matlab实现-Spread Spectrum CDMA despreading, using Matlab achieve

pn和gold码产生的MATLAB程序，该程序提供灵活的码长和生成多项式入参-pn gold yards and the MATLAB program, which provides flexible yards long and income generating polynomial Participation

该源程序代码实现了如：纯ALOHA，扩展ALOHA,CSMA,ISMA等的多径通信协议通信仿真实现，程序结果给出了各个通信协议下传输数据的成功率和时间延迟。-Realize that the source code such as: pure ALOHA, the expansion of ALOHA, CSMA, ISMA and other multi-path communication protocol communication simulation realize, given the results of the proceedings of various communication protocols to transmit data under the success rate and time delay.

高斯脉冲的频谱分析。近似计算并画出高斯脉冲的前15阶导函数的ESD。-Gaussian pulse spectrum analysis. Approximate Gaussian pulse is calculated and drawn 15 of the first derivative function of ESD.

个人认为比较使用的几个VHDL源码之四multiplexer的源码-personally think that the use of the relatively few VHDL source 4 multiplexer the source
