Simulation of the real time traffic signals

用matlab实现对语音信号的短时分析，包括清音和浊音的判决，基音周期的估计。(Using matlab to realize short-time speech signal analysis, including the voiceless and voiced the decision, pitch period estimation.)

用于matlab 的地理分析包。 最新版，1.4f(M_Map is a set of mapping tools written for Matlab v5 and later. These include: Routines to project data in 19 different spherical projections (and determine inverse mappings) A grid generation routine to make nice axes with limits either in lat/long terms or in planar X/Y terms. A coastline database (with 1/4 degree resolution) A global elevation database (1 degree resolution) Hooks into freely available high-resolution coastline and bathymetry databases)

Mapping and Demapping technique for Alamouti coding in Matlab command line.

加有高斯白噪声的两个正弦信号的的观测数据，分别用最小二乘法和总体最小二乘法估计其功率谱，并对两种方法的谱分析进行了比较(Plus a Gaussian white noise of the two sinusoidal signals of observational data, were used least squares and total least squares method to estimate the power spectrum, and spectral analysis of the two methods were compared)

This MATLAB Code plot the aperture efficiency Vs the subtended angle. The user determine the value of n and the code plot and tell what is the angle value that achieves max efficeiency and the value of this efficiency.
