π-TFSK相移时频调制信号及其数学模型

π-TFSK Eime Erequency Phase Msolulation Signal and its Modeling

摘要: 在移动通信中,特别是高速移动数据传输情况下,由于高速移动而产生的衰落以及多径波的干扰,传输特性及差错率特性恶化.相移时频调制正是为了对抗衰落与多径延迟而产生的.本论文主要讨论时频调制信号及其相关函数,并建立了π-TFSK相移时频调制信号的数学模型.

Abstract: In mobile communications,especially for fast moving data transmitting,the transmitting and symbol error rate characteristics will be badly destroyed owing to the fading created by fast moving and interferences caused by multi-path propagation.To eliminate the fading and multi-path delay,Time-Frequency-Phase Modulation(TFPM) has been proposed.This paper mainly discusses the Time-Frequency-Phase Modulation signal and its auto-correlation function.The mathematical model of π-TFSK is also established.
