Abstract
We propose two narrowband interference cancellation algorithms for OFDM based Wireless Local Networks. The first consists of adapting the constellation sizes of the carriers to their Signal-to-Interference-plus-Noise Ratio (SINR). The second relies on a spreading sequence to exploit frequency diversity. The BER performance in the indoor multipath channel is evaluated by simulations using a very flexible model of typical narrowband interference. The channel is modeled based on a ray tracing approach. Both interference cancellation algorithms provide an excellent robustness against the frequency selectivity of the multipath fading channel and strong narrowband interference.
