uwb基础源码，包括uwb信号产生、各种调制方法、信号功率谱密度频谱特性、以及信道仿真等。-uwb basis of source, including uwb signal generator, various modulation methods, the signal power spectral density spectrum, and channel simulation.

OFDM 的全套程序， 包括调制， 解调， 误码， 眼图， 功率谱-OFDM complete set of procedures, including modulation, demodulation, error, eye diagrams, power spectrum. . .

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。-The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication

method based on Neural Network (NN) technique and accompanied with MMSE (Minimum Mean Square Error), which corrects at the receiver level, the Non-Linear (NL) distortions due to the HPA (High Power Amplifier).-In this paper, we present a meth
