Patent ID: 7729460

Claim:
A method in a wireless communication system of providing timing information for a received transmit signal, the method implemented in a receiver comprising: correlating, by a signal correlator in the receiver, one or more parts of the received transmit signal with a quantized training signal to obtain one or more correlation results; determining, by a timing unit in the receiver, the timing information on the basis of the correlation results; and detecting, by a false alarm detector in the receiver, incorrect timing information corresponding to a false alarm on the basis of a signal energy contained within a time window of the received transmit signal, wherein: one or more of the correlation results are obtained in the form of estimated channel impulse responses, the signal energy is a channel impulse response signal energy contained in the respective time window of the received transmit signal and is determined for each possible timing instant, the step of determining the timing information on the basis of the correlation results comprises determining the time window containing a maximum signal energy, and the detection of incorrect timing information corresponding to a false alarm is based on comparing the maximum signal energy with a predefined signal energy threshold.
