Abstract
A method for frequency- and time-selective interference suppression for a communication system based on OFDM, and a receiver therefor. To achieve a much lower bit error rate at the output of the receiver or to permit greater interference or a lower signal-to-noise ratio (in a prior art L-DACS1 receiver, at least 45 nautical miles) for the same transmission power, the invention provides: a filter bank pulse blanking method FBPB in which the sampled received signal is applied to a blanking unit for frequency-selective pulse blanking, which blanking unit consists of an analysis filter bank having M sub-bands; a module for frequency-selective pulse blanking of the sub-band signals; and a synthesis filter bank, which reassembles the signal. The analysis filter bank, which breaks down the received signal into multiple sub-bands on a frequency-selective basis, is used before OFDM windowing, such that the sub-band breakdown applies pulse blanking on a sub-band-selective basis.
