Basestation architecture supporting baseband frequency hopping utilizing time division multiplexed mapping between a radio transceiver and digital signal processing resources

摘要

A wireless telephone architecture employs a broadband transceiver that is coupled to a digital channelizer and digital combiner, such as may employ a real-time Fast Fourier Transform, to extract or combine a set of simultaneous baseband signals. The baseband signals which represent physical channels are mapped to a bank of digital signal processors representing logical channels according to a mapping instituted at the initialization of the call. The mapping is changed on a periodic basis to follow a predetermined frequency hopping schedule. Frequency hopping is thus enabled in a statically tuned broadband transceiver.
