clippin 和过滤技术，能够减少在 OFDM 峰均比
该项目用于降低 PAPR ofdm 系统中，通过使用不同的技术。OFDM 峰均功率比的主要缺点是降低系统性能，因为它在 ofdm 到平均功率高的高峰。并且在这里我们使用非线性压扩变换来减少此峰均比。剪切和过滤技术是对于降低峰均功率比最有用。

dbpsk调制解调程序
SYMPCHUNK sets the number of symbols demodulated at once with a constant carrier frequency and symbol timing offset. This is a fundamental decoder parameter that establishes its carrier and symbol timing tracking bandwidth. Set it too low and the demodulator can"t accurately determine carrier frequency and symbol timing on a noisy signal. Set it too high and the demodulator may not be able to track large symbol rate offsets caused by Doppler shift and/or A/D or spacecraft clock errors. Or it might have trouble tracking high rates of change in the carrier frequency due to Doppler acceleration.The current value of SYMPCHUNK is 4*N1 = 512, where N1 = 128 is the order of the convolutional interleaver. 512 symbols is 512 milliseconds at 1000 symbols/sec, giving a frequency/time determination SNR that is 10*log10(512) = 27 dB greater than the Es/N0, not counti
