The performance evaluation of different PPM demodulation schemes employed in PPM based IR-UWB receivers designed to meet the specifications of the IEEE 802.15.6 Standard are presented. The four different PPM demodulation schemes have been investigated for the demodulation of the standard based transmitted signal specific to the PHY layer.
The performance evaluation is carried out for two different WBAN channel models. Simulation results shows that, the hopping energy detection scheme gives the better performance compared to the other demodulation schemes. The Bit Error Rate (BER) as well as the Packet Error Rate (PER) simulation results are computed and found that the results meets the specified limits.
