Abstract :
A family of ISI free polynomial pulses that can have an asymptotic decay rate of t-k for any integer value of k has been proposed. The proposed family provides flexibility in designing bandlimited pulses in accordance with the desired application, even after the roll-off factor α has been chosen. Pulses obtained from this family have been found to be better than the currently known good pulses.
