Patent ID: 8681893

Claim:
A method comprising: generating an In-phase (I) pulse for an In-phase Quadrature-phase (IQ) constellation symbol using a pulse look-up-table, the I pulse comprising a first half of I pulse samples and a second half of the I pulse samples, the generating an I pulse comprising retrieving the first half of the I pulse samples from the pulse look-up-table in order and retrieving the second half of the I pulse samples by retrieving the first half of the I pulse samples from the pulse look-up-table in reverse-order, the retrieving occurring in less than one symbol period; and generating a Quadrature-phase (Q) pulse for the IQ constellation symbol using the pulse look-up-table, the Q pulse comprising a first half of Q pulse samples and a second half of the Q pulse samples, the generating a Q pulse comprising retrieving the first half of the Q pulse samples from the pulse look-up-table in order and retrieving the second half of the Q pulse samples by retrieving the first half of the Q pulse samples from the pulse look-up-table in reverse-order, the retrieving occurring in less than the same symbol period, wherein the I pulse and the Q pulse are combinable into a transmittable signal.
