Abstract
This invention relates to a method of estimating a characteristic of a signal such as a time of arrival or a transmitter identity in particular in a cellular communication system. Most known techniques have limited performance as they rely on limited amounts of known data. The method of the invention comprise a first step (,) of receiving the signal at a subscriber unit. In a second step (,) the subscriber unit receives assistance data from the fixed network and in a third step (,) an expected signal is derived in response to this assistance data. For GSM the assistance data can be a frame number and a BSIC permitting an entire expected SCH burst to be derived. In a fourth (,) step the signal characteristic is determined by correlation of the received signal and the expected signal. The invention is particularly applicable to location determination in a GSM communication system.
