A Low-complexity Acquisition Implementation for the Modernized GNSS Hardware Receivers

Rentian Ding, Liyan Li, Jie.Zhong, Minjian. Zhao

Abstract:	The paper proposes a low-complexity acquisition implementation for new Global Navigation Satellite System (GNSS) signal. The implementation is based on the Bit Transition Cancellation (BTC) method and the improved Parallel Differential Matched Filter (PDMF) method. The new method eliminates the influence of bit transition with a lower complexity implementation. The result shows that the proposed implementation can provide improved performance compared with other acquisition method. The addition number consumption can reduce 90% compare with the conventional method while the detection probability is greatly improved.
