الملخص الإنجليزي

Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications.

It can provide large data rates with sufficient robustness to radio channel impairments. The demand for high-speed mobile wireless communications is rapidly growing.

OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near This thesis presents an investigation into wavelet based Orthogonal Frequency Division Multiplexing (OFDM) WLAN IEEE.802.11.a system.

As part of this, an investigation of detrimental effects on OFDM is presented, showing the effect of: Additive White Gaussian Noise (AWGN), Multipath effects on the performance of WLAN system. Different modulation techniques are used and simulated to study the performance of the proposed system such as BPSK, QPSK, 16QAM and 64QAM. The performance using DWT-OFDM is better than FFT-OFDM using Haar orthogonal wavelet.

The performance of FFT-OFDM using 64-QAM is worse than using 16-QAM but the performance of DWT-OFDM changed in positive way.
