Abstract:
A wireless multichannel broadband base station (BBS) for a cellular communications network, comprising:a broadband transceiver for providing upconversion and downconversion between an RF band of interest and an intermediate frequency (IF);a transmultiplexer (XMUX) interfacing with said transceiver, said XMUX demultiplexing a single wideband IF receive signal to form a set of individual frequency channels on a receive path of said transceiver, said individual frequency channels comprising a plurality of single data channels, said XMUX also multiplexing said frequency channels into a single wideband IF transmit signal on a transmit path;a bus interface processor interfacing with said XMUX for converting between at least one of said frequency channels and said plurality of single data channels;a communications bus transporting modulated baseband signals for each of said plurality of single data channels between said bus interface processor and any of a plurality of channel processors (CP), each CP for processing any of a plurality of traffic channels contained on any of said baseband signals.
