Abstract :
In a multiuser channel signals are corrupted due to Additive White Gaussian Noise (AWGN) and Inter Carrier Interference (ICI). Orthogonal Frequency Division Multiplexing (OFDM) receiver detects the symbols or bits and estimates the parameters. Wavelet Packet Modulation (WPM) is applied to the received symbols that have been previously coded at the transmitter by a special code. The final result obtained is a reduction of the noise (denoising), which results in performance improvement of bit error rate of the system.
