What is Enhancing OBR and BER in Companded OFDM about?
Companding transforms useful under assumption of infinite bandwidth. Under band limited conditions OBR parameter filters out. So bandwidth is a factor that decides the filter-ing out OBR on the performance of companded OFDM sys-tems. As a result filtering becomes essential under band lim-ited conditions in turn this does deteriorate the system per-formance significantly. In this paper method proposed to overcome the performance degradation. Method called non symmetric scheme based on the use of curve fittin
