An interference cancellation algorithm for fourier-based and wavelet-based OFDM systems

An Interference Cancellation Algorithm (ICA) for both Fourier- and wavelet-based OFDM is proposed. In this study we investigated both an ideal case as well as a non-ideal case of our system. In the ideal case we assume the reference signal is an unwanted sinusoidal signal (the input to our ICA algo...

An interference cancellation algorithm for fourier-based and wavelet-based OFDM systems
description An Interference Cancellation Algorithm (ICA) for both Fourier- and wavelet-based OFDM is proposed. In this study we investigated both an ideal case as well as a non-ideal case of our system. In the ideal case we assume the reference signal is an unwanted sinusoidal signal (the input to our ICA algorithm). In the non-ideal case, we assume the received OFDM signal is contaminated with sinusoidal interference. Simulation results performed at a SNR of 5d8 resulted in an error measurement of 0.01812 for wavelet OFDM and an error of approximately 0.03277 for Fourier-OFDM for the ideal case and for the nonideal case an error of 0.01817 was measured for wavelet-based OFDM and 0.03167 for Fourier-based OFDM. This indicates that the proposed leA exhibits outstanding performance since the results obtained in both cases are almost the same. The waveletbased OFDM outperformed the Fourier-based OFDM in both cases.
