Description: 在给定SNR下，先产生一个原始信号（单音或者BPSK基带信号）然后通过不同信道，如AWGN，Rayleigh等等，再根据给定的平均SNR叠加高斯噪声， 再进行能量检测，对叠加信号求功率累积并对噪声功率进行归一化，然后由Pf反推一个检测门限Th，将累积功率与门限比较，求超过门限次数即为检测概率。由此进行Monte-Carlo仿真画出Pm-Pf曲线，并与理论曲线进行比较。

Description: There are two files in the zip folder. bpsk_spread.m and jakesmodel.m
Steps for simulation:
1] Run jakesmodel.m first
2] Then run bpsk_spread.m .
3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented
4] The resulting performance is stored in BER_awgn.
5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file.
6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable.
7] Run the simulation.
To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray
>>semilogy([1:8],BER_awgn(1:8), g* )
hold on
semilogy([1:8],BER_ray(1:8), -.b* )
hold on
grid on
