Abstract
In this paper, an acquisition algorithm is discussed in parallel combinatory spread spectrum (PCSS) system. The algorithm model is first built. Then, an improved algorithm utilizing multiple correlation peak accumulation under low SNR is proposed. The simulation results show that Doppler offset and PN code-phase delay can be obtained by using the proposed acquisition algorithms. The simulation results also represent that a good performance of detection probability can be obtained by adjusting the number of PN code period in low SNR.
