摘要: 該文提出了一種廣義時(shí)頻二維擴(kuò)頻的概念。在加性白高斯噪聲信道中,給出了這種二維擴(kuò)頻通信方式的發(fā)射機(jī)、接收機(jī)工作原理,分析了二維擴(kuò)頻通信方式的誤比特率,同時(shí),給出了二維擴(kuò)頻通信方法的誤比特率的仿真結(jié)果.結(jié)果表明,分析結(jié)果與仿真結(jié)果相近。

Abstract: In this paper, a conception of general time-frequency domain 2-Dirnensional Spread Spectrum (2DSS) is proposed. The principles of the transmitter and receiver of the 2DSS communications for additive white Gaussian noise channels are discussed, the Bit Error Rate (BER) of this scheme is also analyzed. The simulation result of the BER of the 2DSS communications is provided. It shows that the simulation result and analyzed result are almost the same. -
