In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on the other hand, is designed to encode a stream of information by spreading the encoded data across as much of the frequency spectrum as possible. This allows the signal reception, even if there is interference on some frequencies. While there are many variations on spread spectrum communication, we concentrated on Direct Sequence Spread Spectrum encoding (DSSS). The DSSS method spreads the signal by multiplying it by a chip, a maximal length pseudorandom sequence modulated at a known rate. Since the host signals are in discrete-time format, we can use the sampling rate as the chip rate for coding.

可以试试对毕业设计有没有中意的作用，做的是手势识别系统的设计，matlab中文论坛看到，可以试试(You can try the graduation design no favorite role, do gesture recognition system design, matlab Chinese forum to see, you can try)

说明：  使用K-L算法进行特征变换，画出结果图像(Feature transformation, using the KL algorithm to draw the resulting image)

Clear out structures. This also intializes the command queue to all DBRI WAIT s since the WAIT opcode is 0.

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)

基于雷达信号处理的仿真实现实现，是一个和前任研究不同的代码。(Radar signal processing based on the implementation of the simulation implementation, is a former research and different codes.)

DC-DC simulink建模，有初级的详细建模步骤，开环、闭环建模，包块了buck, boost， buck-boost的建模，以及瞬态分析(DC-DC buck，boost，buck-boost modeling on simulink, close loop and open loop modeling, transient analysis)
