DCSK的分集接收反相解调方案
Diversity reception and inverting demodulation scheme for DCSK
摘要
Abstract
In this paper, a diversity reception and inverting demodulation scheme for DCSK in Rayleigh multipath fading channels is proposed. In the scheme, transmitting signals are delayed appropriately to generate multi-channel signals, and then addition and reverse operation are performed on them. And the receiver end makes decisions according to the opera-tion results. Theoretical analysis and simulation results show that DCSK communication system based on the diversity recep-tion and inverting demodulation scheme makes some improvement, compared with the classical DCSK communication system. Also, it can effectively suppress noise.关键词
