  • For improving the bandwidth efficiency, a sinusoidal modulated method based on Prolate Spheroidal Wave Functions(PSWF) is proposed. The basedband modulated orthogonal waveforms is designed based on PSWF, which is time-limited and band-limited approximately. The orthogonal waveforms spectrum is mixed or overlapped in frequency domain. The information is modulated by multi-plexing baseband modulation. The spectrum shifting is achieved by sine carrier modulation. By simulation and analysis, the system bandwidth efficiency can be fast closed to 2 Baud/Hz and the approximating speed is greater than that of OFDM system, the power efficiency is better as well. The modulation method is easily realizable.
