Abstract: Frequencies are allocated to plural base stations for managing cells of a cellular wireless telephone network by a computer which for a given cell, allocates a frequency associated with an estimated minimal interference, and selects another cell of remaining cells to be processed. The computer (1) develops a chain of downstream cells within mutual radio range by repeating the above steps for each cell, (2) compares estimated interference levels with a threshold, (3) defines a remainder of cells by eliminating from the remaining set of plural cells to be processed, cells associated with an interference level less than the threshold, (4) develops a first segment of a chain of cells of allocated frequencies when the remaining cells have been defined, and (5) develops a second chain segment by allocating frequencies to the unprocessed remaining cells by searching for other frequencies to be allocated to the remaining cells by iterating these steps until no cells remain.

Abstract: A method and device for the testing of a radiocommunications network by implementing downline from a first antenna and a second antenna, respectively a first reception line and a second reception line. The first reception line is assigned to the reception of first signals, in a first incoming direction. A second reception line is assigned to the reception of second signals, in a second incoming direction. Each reception line tries to decode the signals that it receives and, if the decoding can be done, it reads an identifier proper to the transmitter, so as to determine firstly which of said first and second signals are interference signals, and, secondly, the incoming direction of interference signals and/or the identifier of interference units. The disclosure also relates to a corresponding base station.

Abstract: A mobile radiocommunication terminal includes a first antenna with a first polarization and a second antenna with a second polarization. The antennas are separate and are both used to receive signals. Signals received by the first and second antennas are combined in polarization diversity. Specifically, for each distinct polarization, a Viterbi decoding means outputs the most probable signals and a probability factor associated with the most probable signals. A digital signal processor includes, for each distinct polarization, weighting means that weight the most probable signals by the associated probability factor, and means for summating the signal outputs from the weighting means.
