Abstract
Described herein is a method of enhancing signals received by a receiver in a mobile telecommunications network. The method comprises correlating the received signals to produce a correlation and making a selection from the correlation to create a replica for enhancing the received signals.
Claims12
A method of enhancing signals in a mobile telecommunications system, the system comprising a base station and first and second receivers within a reception zone of the base station, each of said first and second receivers operable with a dedicated antenna, both of said first and second receivers being connected to a correlator, the method including:
- a) receiving, from the base station, a first plurality of signals at the first receiver at a first location, the first receiver having a good quality communications link with the base station;
- b) receiving, from the base station, a second plurality of signals at the second receiver at a location separate from said first location;
- c) correlating the received signals from both receivers to provide an estimated correlation therefor;
- d) selecting areas from within the estimated correlation;
- e) creating a replica of unwanted signals using said selection and said first plurality of signals;
- and
- f) enhancing said second plurality of signals by eliminating said replica therefrom.
A system for defining propagation characteristics of a cell within a mobile telecommunications network, the system comprising:
- a base station, a first receiver and second receiver within a reception zone of the base station, the first and second receivers each being associated with an antenna and both being associated with a correlator, said first receiver at a first location configured to receive a first plurality of signals from the base station on the mobile telecommunications network, said first receiver having a good quality communications link with the base station said second receiver at a second location separate from the first location configured to receive a second plurality of signals from the base station;
- means for generating an estimated correlation of the first and second pluralities of signals;
- means for selecting an area from within the estimated correlation;
- means for creating a replica of an unwanted signal using the selected area and the first plurality of signals;
- and
- means for enhancing the second plurality of signals by eliminating the replica of the unwanted signal therefrom.
