HCS300编码。。还要最少20个字？够了吧？？(HCS300 code. . But also at least 20 words? Enough, right? ?)

说明：  自己用matlab编写的ofdm程序。供大家交流学习。(Written with matlab ofdm own procedures. For everyone to share their knowledge.)

对EBPSK(Extended binary phase shift keying)调制雷达系统的特点，本文将其与传统的LFM(Linear frequency modulation)雷达系统进行综合性能比较。(he overall performances of EBPSK(Extended binary phase shift keying) modulation and LFM(Linear frequency modulation) radar systems are compared. First, the target detection performance base on CFAR(Constant False Alarm Rate) of two systems are analyzed under several conditions. As the time-delay is relatively large, the detection performance of EBPSK modulation radar system is better than LFM radar system. EBPSK modulation signals can combat the effect of Doppler spread on system performance in HF(High Frequency) channel.)
