Abstract [en]

In this paper, we propose a qualitative comparison between OFDM (Orthogonal Frequency Division Multiplexing), and WPM (Wavelet Packet Modulation). The comparison is done for two separate cases. Firstly, the efficiency of the two signaling systems will be compared. Secondly, the requirements for hardware implementation will be performed. From the performance and the VLSI implementation viewpoint, we found that WPM outperforms OFDM. However, the out-of-band radiation and peak-to-average-power for the case of OFDM is better compared to the WPM. The extensive simulation results, show that the average increase of peak-to-average-power is approximately 0.98dB compared to the OFDM. The increase of the adjacent channel power ratio channel is approximately 12.41dBc compared to the OFDM.
