papr_windowing
reduction to papr in ofdm with Peak Windowing:
The basic idea of peak windowing is to multiply the envelope of OFDM
signal with a weighting function . Therefore,
~xE (t)= xE (t) f (t)
where
XE(t) =[x(t)]
The weighting function given by:
f (t)= 1-Σ α .w(t- t )
t-t
w(t) : is the window function.
t : denotes the position of a local maximum of the envelop xE(t) .
α : attenuation constant .
When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal.
Hanning window function will be used for w(t)
As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.

test_uncoded_BPSK
说明： 未编码传输AWGN信道测试
每帧的输入是相同的，（不是每帧都不一样，这样可以大幅降低计算量）
在帧比特足够多的情况下，应该可以保证随机性(AWGN channel is not coded transmission test input of each frame is the same, (not every frame is different, this can significantly reduce the computation) are enough bits in the frame of the case, should be able to guarantee randomness)
