The Performance of Generalized Time-Frequency Domain Two Dimensional Spread Spectrum in AWGN Channel

该文提出了一种广义时频二维扩频的概念。在加性白高斯噪声信道中,给出了这种二维扩频通信方式的发射机、接收机工作原理,分析了二维扩频通信方式的误比特率,同时,给出了二维扩频通信方法的误比特率的仿真结果.结果表明,分析结果与仿真结果相近。

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.
