Abstract:
A method for increasing the sensitivity of a receiver, comprising the steps of: receiving in the receiver a first signal having at least one data boundary from an external source; receiving in the receiver, from a second source, an aiding message containing information regarding at least one of the data boundaries within the first signal; applying correlation codes to the first signal to yield correlation data; accumulating the correlation data yielded by applying the correlation codes over a first interval preceding a first one of the data boundaries for which information was received from the second source yielding a first accumulation result; and accumulating the correlation data over a second interval following the first one of the data boundaries for which information was received from the second source yielding a second accumulation result, the timing of the first and second interval being based upon the knowledge of the timing of the at least one data boundary ascertained from the aiding message.
