| 摘 要： | 各种混沌键控数字调制方案中,DCSK调制有着最优的抗噪性能,而且由于混沌信号内在的宽带特性使其具有很强的抗多径干扰能力。通过多径衰落信道中的理论性能推导结果和仿真表明,经改进的DCSK虽然与原DCSK有相同的性能,但从多址系统收发信机结构来看,其却具有易于实现的优点。

| Abstract: | The performance of DCSK is the best one in chaotic digital modulation schemes in the AWGN channel.It is also robust to multi-path fading because of the wideband property inherited by chaotic signal.from theoretical eduction and simulation the performances of the modified DCSK and DCSK are identical.But in view of multi-access system transceiver complexity,the modified DCSK is superior to DCSK. |
