An improvement of Broadband PLC channel based on PS-OFDM

Various of multicarrier modulation scheme may be used to bit rate increases of Broadband PLC channel. One of the schemes is the Pulse-Shaped OFDM (PS-OFDM). There is an important parameter in the PS-OFDM that influence the increasing in bit rate on the PLC channel, the guard interval, and the number of subchannels. This paper discusses performance of the system against the effects of code rate, multipath propagation channel on Broadband PLC channel, and the effect of the guard interval of data transmission speed. Simulation results confirm that PS-OFDM technique offer a fine performance, where minimum BER achieved on 22 dB up to 24 dB of SNR, and maximum data rate on 41,033 Mbps, achieved for 16-QAM mapper by 1/16 guard interval.
