OLCD: Optimal Linear Combinational Detector in GNSS Signal Acquisition

Y. Liu, B. Li, X. Tang, F. Wang

Abstract: Signal acquisition is a process of two-dimensional search in time/frequency domain and signal detection in multiple search bins. The hypothesis testing of current signal acquisition algorithms are made according to correlation of a single bin; however, according to the effect of code phase and Doppler frequency error, signal presence could be detected on multiple bins. Based on the principle, the optimal linear combinational detector (OLCD) without increasing the hardware complexity is proposed. At last, simulation result with common acquisition parameters shows that the acquisition performance of OLCD is about 1dB better than that of traditional detector.
