Spectrum Sensing using ED for DSB signal

HI GUYA CHIT UAING MATLAB WE USE METOD LSB PLS CHECK IT VERY SEFULL

(1) 产生数值为±1的用户随机数据；给出Matlab下对应的模块； (2) 产生并给出64×64的Walsh矩阵，作为用户接入的扩频码； (3) 利用上述一个用户的扩频码和用户数据演示扩频过程；给出Simulink工作框图； (4) 利用FFT，计算并画出基带数据和扩频信号的频谱（在一个图中给出）； ((1) value of ± 1 generated random data users given under the corresponding Matlab module (2) generation and gives the Walsh 64 × 64 matrix, as the user access to the spreading code (3) the use of the a user' s spreading code and spread spectrum user data presentation process given work Simulink block diagram (4) the use of FFT, calculate and draw the base-band spectrum data and the spread spectrum signal (given in a diagram) )

说明：  用随机数发生器产生二进制序列，他作为FSK调制器的输入。FSK调制器的输出受到概率a的加性高斯噪声污染，仿真得出系统的误码率。( Has the binary sequence with the random number generator, he takes FSK modulator s input. The FSK modulator s output receives probability the Canada Gauss noise pollution, the simulation obtains system s error rate. )

搭建了一个OFDM系统，并用基于导频的方式进行了信道的估计，最后画出了系统在3条径下的瑞利信道时误比特率随信噪比的变化。(bulid a OFDM system,make channel estimation based on pilot signal,finally,plot ber when SNR changed)

关于D2D通信的仿真,仿真包括吞吐量本算法与随机算法等进行了对比。(Simulation of D2D communication)
