Simulation DS-SS Rake Receiver

用MATLAB实现dpsk信号调制，载波信号(Using MATLAB to achieve dpsk signal modulation, the carrier signal)

Convert from latitude, longitude, and altitude (geodetic with respect to the WGS-84 ellipsoid) to a position vector in the Earth-centered, Earth-fixed (ECEF reference frame.

矩陣案例，主要是以matlab軟件來運算標準題型。(Matrix case, mainly matlab software to compute the standard questions.)

General Information for MECL 10H and MECL 10K

In this simulink model , QPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

c code for LHMs and using the matlab to plot the field

#include <iostream> #include <stdlib.h> #include <string.h> using namespace std const kl = 4, kzs = 2, m = 6, n = 4, Error = 5 char *K[kl] = {{"01"},{"bB"},{"23456789ACDEFacdef"},{"hH"}} int A[m][n] = {{1,2,2,5}, {1,3,2,4},{2,2,2,4},{2,2,2,4},{5,5,5,5},{5,5,5,5}},

统计计算的一些小函数，求均值，方差，相关系数，SSE，SSR，SST等等(Statistical computing, some small function, find the mean, variance, correlation coefficient, SSE, SSR, SST, etc.)
