Low-power signal acquisition for galileo satellite navigation system

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
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.
