The paper describes a Software Defined Radio architecture that simultaneously demodulates all radio stations in the Frequency Modulated (FM) band, and is intended as a preprocessor for content and metadata indexing applications. The system, which contains an overlap-add type channelizing filterbank and a massively parallel frequency demodulation block, is implemented in a single Field- Programmable Gate Array, thus offering the possibility of replacing more traditional media indexing installations containing tens of individual receivers. It is believed to be the first single chip full-band channelization system intended for consumer broadcast media indexing applications. Chip resource utilization details and experimental results from the developed system are also presented.
