| 摘 要： | 为改善短波通信的质量，针对短波宽带信道时变衰落特性和短波高速传输的需求，设计了速率为2400～14400bps的传输波形。该方案结合优异纠错性能编码LDPc码进行波形设计，仿真结果表明：在AWGN信道条件下，所设计的波形方案均比美军标110C性能优越，最高能够提供3dB的增益性能。

| Abstract: | For improving the quality of the short-wave communication,in view of the characteristics of the short-wave broadband time-varying fading channe~ and short-wave high-speed transmission waveform. The scheme is designed with the excellent performance of erorrs correction LDPC code,the simulation re- suits show that,under the condition of AWGN channel the designed waveform scheme is better than the performance of MIL-STD-188-110C,it can enhance 3 dB performance at best. |
