A digital channelizer unit is proposed for a satellite digital payload capable of processing multiple digital input signals. The input signals are downsampled and converted to complex baseband signals for processing with the digital channelizer unit. Each complex baseband signal is then channelized into...http://www.google.de/patents/US7675985?utm_source=gb-gplus-sharePatent US7675985 - Digital channelizer unit for processing multiple digital input signals
