摘要:

为估计重叠时分复用(OVTDM)系统性能,采用基于数值计算的方法,推导了加性高斯白噪声(AWGN)信道中符号为二相调制(BPSK)、采用最大似然(ML)准则时, OVTDM系统的一个性能界(称为修正一致界). 仿真结果表明,在误符号率(SER)为10-6时,该界与实际系统的归一化信噪比误差不会超过3?dB.

关键词: 重叠时分复用, 符号间干扰, 修正一致界

Abstract:

An upper bound of overlapped time division multiplexing (OVTDM) system in additive white Gaussian noise(AWGN) channel with binary phase-shift keying (BPSK) modulation named modified union bound is given using the maximum likelihood (ML) rule. The bound approaches the real performance by no more than 3?dB at a symbol error rate(SER) of 10-6 in the simulation.

Key words: overlapped time division multiplexing, inter symbol interference, modified union bound
