Abstract: A system and method for processing signals from at least two sources, using a receiver having a timer and a local code sequence, the method comprising, providing at least one signal channel divided into a plurality of sequential time slots processing said signal from a first of said two sources in a first time slot of the plurality of time slots to provide a first time slot signal, processing said signal from a second of said two sources in a second time slot of the plurality of time slots to provide a second time slot signal, processing said signal from said first of said two sources in a third time slot of the plurality of time slots to provide a third time slot signal, said first, second and third time slots occurring in sequential order, comparing said local code sequence to said signals in said first and third time slots by incrementing the local code sequence during the interval between said first and third time slots.
