Paper Abstract
OFDM technology contains several terminologies, transform algorithms for communication engineering.
In this way Companding transforms useful under assumption of infinite bandwidth. Under band limited conditions
Out of band radiation (OBR) parameter filters out. So bandwidth is a factor that decides the filtering out OBR
on the performance of companded OFDM systems. As a result filtering becomes essential under band limited conditions in turn this does deteriorate the system performance significantly. In this paper method proposed to overcome the performance degradation. Method called non symmetric scheme based on the use of curve fitting method to find out a suitable polynomial to be used for decompanding at the receiver. This method indeed improves the performance in comparison to existing symmetric methods when filtering is necessary for band limited conditions.
