Wideband wireless basestation making use of time division multiple-access bus having selectable number of time slots and frame synchronization to support different modulation standards

A wideband basestation transceiver including:

• a wideband digital tuner that provides a wideband digital signal at an output;
• a digital channelizer, connected to the wideband tuner, to produce a plurality of sampled channel signals, with each channel signal representing signal energy in one of a plurality of radio frequency channels serviced by the basestation;
• a time division multiple-access, TDM, data bus;
• means for selectively connecting the digital samples of each channel signal, in turn, to the TDM bus;
• basestation controller means, for controlling the means for selectively connecting the digital samples of each channel signal to the TDM bus, by so connecting each channel signal in a predetermined timeslot, in a predetermined order;
• means, coupled to the TDM bus, for selecting the digital samples in a particular timeslot, and for generating a reconstructed channel signal thereby;
• means for allocating a demodulator to be coupled to the reconstructed channel signal when the associated radio frequency channel is active, the demodulator providing a demodulated channel signal;
• means for allocating a T1 line encoder to the demodulated channel signal, to format the demodulated channel signal for transmission over a T1 span line;
• and
• synchronization and clock generation means, connected to the base station controller means, for selecting a number of time slots, as well as a bus frame rate to be used on the TDM bus, such that the number of time slots and the bus frame rate depend upon, respectively, the number of the channel signals and the bandwidth of each of the channel signals provided by the digital channelizer.
