Abstract:
A base station for processing signals in a multiple mobile subscriber unit wireless communication system comprising:an antenna for receiving signals from a plurality of the mobile units as a composite radio frequency, RF, signal;wideband digital tuner means, connected to the antenna, for downconverting a selected bandwidth of the RF signal to an intermediate frequency, IF, and for performing an analog to digital conversion on the IF signal, to provide a wideband digital tuner output signal;digital channelization means, being connected to receive the wideband tuner output signal, and providing multiple digital channel signal outputs, each digital channel signal output having a predetermined channel bandwidth, and each digital channel signal corresponding to one of the signals received from one of the mobile units;a plurality of digital signal processing means, for providing digitally processed channel signal outputs;data switching means, disposed between the multiple digital channel signal outputs and the plurality of digital signal processing means, the data switching means for interconnecting any one of the multiple digital channel signal outputs to any one of the plurality of digital signal processing means; andcontrol message routing means, connected to each of the plurality of digital signal processing means, the control message routing means for routing control messages among the plurality of digital signal processing means, the control message routing means including:(i) master digital signal processing means for generating control messages;(ii) a plurality, C, of primary message communication means, each including a plurality, R, of primary input/output interfaces, each such input/output interface associated with one of a number, R, of digital signal processing means arranged in a column;(iii) control logic means, disposed between the master digital signal processing means and the plurality of primary message communication means, for routing the control messages to one of the plurality, C, of primary message communication means connected thereto; and(iv) a plurality of secondary message communication means, each associated with a number, C, of digital signal processing means arranged in a row, for communicating control messages between digital signal processing means located in the row.
