This paper concerns with an optimal pulse shaping filter in time-discrete multipath Rayleigh fading environment. The shift orthogonal pulse shaping filter is proposed and proved to be the optimal envelope in the sense of least average bit error probability. It is suited to the Rayleigh fading channel with an arbitrary strength/delay profile of multiple time-discrete paths for BPSK and QPSK signaling etc. Numerical results show that shift orthogonal waveform based pulse shaping filter has lower bit error rate than general shaping waveforms such as square root raised cosine (SRRC) waveform.
