Abstract
En 中文
Precise target localization is pivotal in beyond 5G and 6G networks, particularly in location-aware vertical applications. In this letter, we investigate the performance limits for target localization using quantized observations via Fisher information analysis. To account for data transmission delays between agents and the fusion center, we derive the posterior Cramer-Rao bound for target localization in delay-sensitive scenarios and unveil the bidirectional effects of bit-depth on localization accuracy. Then, a bit allocation algorithm is proposed to balance the limited communication resources over the network. Finally, the simulation results validate our theoretical analysis and the effectiveness of the proposed bit allocation algorithm.
