Abstract :
New algorithms for coherent and noncoherent code tracking loops are presented. The algorithms are relatively simple and hardware reduced. Functional identity to the traditionally optimal early-late (E-L) code tracking loops is presented. The new structures are computationally efficient by reducing substantially the multiply and accumulate (MAC) operations per time unit. As a result, reduced power consumption schemes are obtained
