Patent ID: 7602852

Claim:
A method of generating a coarse estimate of a location of an information carrying part of a symbol in a received signal in a telecommunication system, the method comprising: generating correlation values by correlating the received signal with a delayed received signal; identifying a maximum correlation value of the correlation values; identifying a duration in time during which the correlation values are greater than or equal to a predetermined percentage of the maximum correlation value, wherein the duration in time begins at a first moment in time and ends at a second moment in time; setting the coarse estimate of the location of the peak correlation value equal to a moment in time between the first moment in time and the second moment in time, determining an estimated delay spread, T m , associated with the received signal in accordance with T m =2 PW 100−ΔX −PW 100−2ΔX , where: PW 100−ΔX is a first peak width representing a length of the duration of time between the first moment in time when the correlation values are greater than or equal to the predetermined percentage, X, of the maximum correlation value and the second moment in time when the correlation values are greater than or equal to the predetermined percentage, X, of the maximum correlation maximum value; and PW 100−2ΔX is a second peak width representing a length of a duration of time between a first moment in time when the correlation values are greater than or equal to 100−2ΔX % of the maximum correlation value, and a second moment in time when the correlation values are greater than or equal to 100−2ΔX % of the maximum correlation value, wherein ΔX=100−X.
