| Abstract: | 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. |
