  • When the total transmitting power is limited, the authors investigate the effect of different power allocation schemes on the side-information and the arithmetic to obtain the optimal power allocation coefficient for the system with Partial Transmit Sequences (PTS). Besides, the authors propose a new simple arithmetic to obtain the sub-optimal coefficient. The simulation results indicate that reducing a little power on every data carrier will obtain large gain on side-information carriers. With increasing the signal to noise ratio, the system is apt to averagely allocate the total power on every carrier. The bit error rate with the optimal or sub-optimal coefficient is close to the ideal value.
