非正弦时域正交调制性能分析及仿真

摘要

The mathematical model of non-sinusoidal orthogonal modulation in time domain based on Prolate Spheroidal Wave Functions(PSWF)is proposed and the fundamentals are discussed. The mathematical expressions of the data rate-to-bandwidth ratio, the spectrum of modulated signals and the bit-error-rate in Additive White Gauss Noise(AWGN) channel are deduced and the system performance is simulated. Simulation results are compared with the mathematical ones and the theoretical derivation is proved. Results can provide theoretical and practical basis for communication system design.%给出基于时限椭圆球面波函数的非正弦时域正交调制解调的数学模型,从理论上推导调制信号的频带利用率、功率谱特性以及AWGN信道下的差错性能,给出功率谱及误码率的数学表达式,进行仿真并与理论推导结果进行比较,验证理论推导的正确性,为通信系统设计和应用提供理论和实验依据.
