| Abstract | ||
| The proposed model based on Discrete Wavelet Transform (DWT) for OFDM , was suggested to improve the performance of HiperLAN/2 transceiver that lies under the Additive White Gaussian Noise (AWGN), multipath fading,and selective fading channels. This model is used to reduce the effect of multipath fading. The results extracted by a computer simulation for a model proposed, and then it is compared with the original technique for HiperLAN/2 transceiver based on DWT for both systems. As a result, it can be seen from the proposed technique that a high performance improvement was obtained over the conventional HiperLAN/2 transceiver, where the Bit Error Rate (BER) is widely reduced under the AWGN, flat fading, and selective fading channels. | ||
