Wideband bus for wireless base station
First Claim
1. A wideband bus in a base station of a wireless communication system, said wideband bus comprising:
- a plurality of substantially identical consecutively interconnected slots, wherein each of said slots is designed to receive a digital signal processing and data transfer module, and wherein each of said slots includes receiving and transmitting ports for receiving and transmitting communication data from and to adjacent slots, respectively, and sense ports for detecting sense data from adjacent slots; and
,a plurality of data lines interconnecting the receiving, transmitting and sense ports of one slot to the transmitting, receiving and sense ports of an adjacent slot, respectively,wherein the interconnections among the slots provide for grouping consecutive slots into a section,wherein said section comprises a plurality of the consecutive slots, and wherein the slots of said section include digital signal processing modules for performing application specific cell processing operations, said operations including converting received radio frequency (RF) signals to digitized received communication data, digitally filtering the received communication data and converting digitized transmission communication data to RF signals for transmission.

Abstract
A wideband band bus in a base station of a wireless communication system includes consecutively interconnected slots and may be automatically configured into one or more sections that perform application specific cell processing operations, without requiring hardware or software changes to the base station. A section of the wideband bus includes a group of the consecutively connected slots containing digital signal processing modules which implement a cell processing application. The modules included in the slots of a section and the interconnections among the slots provide for diversity reception, expandable cell capacity and cell operations in accordance with wireless communication protocol standards.
