中文摘要

This paper proposes a spatial cooperative diversity and decision-making technique to enhance signal detection and indoor mobile robot positioning performance of a global positioning satellite system (GNSS) receiver. Though the adaptive antenna array technique in early research could effectively promote anti-jamming freedom, overcome time-vary system, and mitigate narrowband and wideband interferences. However, factors such as the decrease of signal magnitude caused by obstacles (especially in the indoor environment), multipath and blanking effect caused by the change in antenna direction with the motion of mobile robot can degrade the detection and interference mitigation performance of GNSS receivers. This paper aims to develop a dynamic cooperative scheme to proceed with the switch, selection, combination, and optimization among antennas. In addition, a signal processing experimental platform is also established to receive actually indoor GNSS signals for verification. The proposed scheme is capable of effectively promoting the post correlation signal-to-noise-ratio (SNR) capability of a GNSS receiver under the indoor environment.
