Title: Means of increasing capacity in cellular radio (mobile and fixed) systems
Inventor: JEFFERIES ANDREW WILLIAM
IPC: H04W16/12
Filed: 1997-08-29
Abstract: The disclosure relates to a method of configuring a plurality of directional beams in a cellular radio system having a plurality of antennas each communicating over a corresponding respective cell area by re-arrangement of directional beams using a same or like carrier frequency to each other, so as to be directed away from each other, and by restricting signal loading on beams experiencing worst case interference. Interference between geographically close cells is reduced by the method resulting in an improvement in carrier to interference ratio performance. Carrier frequencies of inner two beams 32A and 33A transmitted by antenna 35A exchange for inner two beams 32B and 33B which are transmitted in substantially the same direction by antenna 35B. Inner beams experiencing highest interference are restricted so as to operate at below their maximum signal load, in order to reduce interference. This results in an improved carrier to interference performance for all beams and may allow increased frequency reuse. The techniques disclosed are applicable to center-excited or corner excited (tri-cellular) systems.

Title: Automatic frequency correction
Inventor: BRADLEY MARTIN JAMES
IPC: H04L27/00
Filed: 1998-09-12
Abstract: The method for automatic frequency correction is for use in an existing Digital Enhanced Cordless Telecommunications (DECT) system. The method comprises the steps of measuring a phase difference between an output of two correlators which operate on a received signal and employ segments of a known transmitted waveform separated by a known time difference as reference signals, calculating a frequency offset estimate (54) based on said measured phase difference, correcting said received signal (56) by an amount corresponding to said calculated frequency offset estimate, and repeating said measuring, calculating and correcting steps in a plurality of stages (58-64) in order to achieve a predetermined accuracy of said carrier frequency offset estimate. The method will be used in a DECT system in a Wireless Local Loop application which can tolerate multi-path conditions to provide a reliable telecommunication system for use with both POTS and ISDN services. The system will be easy to install and not require a licence, thus making it less expensive than current cordless telecommunication systems.

Inventor: LAAKSONEN ESA
IPC: G11C7/10
Filed: 1997-12-10
Abstract: The structure according to the invention employs a latch circuit without a reset input as a structural unit for memory. The memory structure's input bus is duplicated and the value of the first bus is forced to "0000" and the value of the second bus is forced to "1111". In a reset state the latch circuits are driven transparent so that each memory bit's reset state depends on which of the buses the latch circuit is connected to. The structure according to the invention fulfils the requirement of an arbitrarily selectable reset state while at the same time the memory can be implemented using the smallest possible elements, i.c. latch circuits without reset inputs.
