Abstract

Abstract

In order to cope with the challenges brought by the fractional delay and synchronization error in 6G wireless channel of positioning systems, this paper proposes a high resolution channel simulation method based on frequency domain equivalent and a high resolution positioning technology exploiting Angle Of Arrival (AOA) information. The former achieves high resolution while reducing the high complexity brought by time domain method due to converting channel tap delays to frequency domain to process, providing solid foundation for accurate simulation of delay information in localization; the later achieves high positioning resolution under synchronization error by combining iterative channel estimation, AOA estimation algorithm based on first arrival path detection and position estimation algorithm with AOA information input. The numerical simulation results show that they both achieve optimized performance in corresponding practical scenarios.
