Abstract
A coarse estimate of a location of an information carrying part of a symbol in a received signal in a telecommunication system is generated. This involves generating correlation values by correlating the received signal with a delayed received signal. A maximum correlation value of the correlation values is identified, and a duration in time during which the correlation values are greater than or equal to a predetermined percentage of the maximum correlation value is identified, wherein the duration in time begins at a first moment in time and ends at a second moment in time. The coarse estimate of the location of the peak correlation value is set equal to a moment in time between the first moment in time and the second moment in time, for example, a midpoint between the first moment in time and the second moment in time.
