In this paper we propose modified raised cosine pulses and a family of modified ISI free and bandlimited polynomial pulses for UWB communication systems which could provide very high data rates not possible by the conventional pulses and other proposed pulse design algorithms. The power spectrum of these proposed pulses fits the FCC spectral mask even for very high data rates and data rates gets quantized for various levels depending upon the shift frequency. Using this scheme and with a certain choice of design variables it is possible to design orthogonal pulses which could be used for multiuser data communication after truncating them for the same time interval.
