Design and Improvement of Hipper LAN/2 Transceiver using Selective Discrete Sinusoidal Transform Technique

Abstract

For this presentation, a new bit error rate (BER) and peak-to-average power ratio (PAPR) alleviation strategy, in HiperLAN/2 transceiver have been advanced as an answer which utilize a particular discrete sinusoidal transform (SDST) in the frequency domain of orthogonal frequency-division multiplexing (OFDM) . The simulation expounds that the recommended strategy can relieve BER and PAPR estimations of OFDM framework using, 16-QAM, modulation and the proposed system can be utilized effortlessly. The simulation results are then contrasted and ordinary discrete Fourier transform (DFT) - based OFDM of routine HiperLAN/2 transceiver. This further showcases that in contrast with ITU multipath channel, the proposed OFDM has improved BER execution. This is additionally where the routine proposed framework is found to accomplish diminishment in the BER and PAPR in examination with the ordinary OFDM framework.
