Base station for a mobile digital system with the frequency hopping technique

Claim 1

A communication base station wherein data associated to each user are transmitted and received as a bit burst in a frame including n users, such frame also containing control data, and the frames are subject to frequency hopping in which each frame is transmitted and received at a frequency changing according to an algorithm among those frames assigned to the area served by said station, said station comprising: a plurality of receiver/transmitters connected to a common antenna through a combining circuit; a plurality of process nodal points connected to a station controller; and a distribution circuit for the baseband control of the frequency hopping including at least a common synchronized bus onto which user's data and said control data are entered and read in time succession at a bit rate higher than that of said bit burst; said receiver/transmitters being connected to said synchronized bus at least through a first set of multiplexing units and a first set of demultiplexing units, said first sets of units being synchronized among themselves with respect to said frequency hopping; said nodal points being connected to said synchronized bus at least through a second set of multiplexing units and a second set of demultiplexing units, said second sets of units being synchronized among themselves with respect to said frequency hopping.
