Abstract
This paper reports the results of wideband channel
measurements conducted on in apartment environments. Two
kinds of channel measurements were performed: impulse
response measurements and noise signal measurements. In
measure based channel model, the performance degradation is
analyzed due to timing synchronization and colored noise in
orthogonal frequency division multiplexing (OFDM) based
power line communication (PLC) systems and then proceeds
to propose a new receiver scheme for channel estimation and
soft decision decoding scheme under imperfect channel
estimation. Simulation results show that the proposed
algorithm can efficiently eliminate the effects of imperfect
channel estimation and colored noise for coded OFDM system.
