Abstract :
In satellite navigation systems based on code division multiple access, the signal acquisition in receiver is a computationally intensive task where the received signal is correlated with long pseudo random noise codes. In this paper, a novel architecture for acquisition of signals with binary offset modulation is proposed. The architecture is modular and has low power consumption due to word-parallel correlation structure.
