Link-level simulator for 5G localization
Xinghua Jia, Peng Liu, Wangdong Qi +5
Channel-state-information-based localization in 5G networks has been a promising way to obtain highly accurate positions compared to previous communication networks. However, there…
On the Unambiguous Distance of Multi-Carrier Phase Ranging with Random Hopped Frequencie
Peng Liu, Wangdong Qi, Yue Zhang +1
In a multi-carrier phase ranging (MPR) system, the distance that radio signal travels is estimated through phase shift of multiple carrier frequencies. Due to phase ambiguity, a un…
Full Duplex Joint Sensing for Opportunistic Access in Spectrum-Heterogeneous Cognitive Radio Networks
Peng Liu, Wangdong Qi, Li Wei +2
In cognitive radio networks (CRN), secondary users (SUs) can share spectrum with licensed primary users (PUs). Because an SU receiver (SU-Rx) does not always share the same view of…
Optimal sequencing of a set of positive numbers with the variance of the sequence's partial sums maximized
Li Wei, Wangdong Qi, Dingxing Chen +2
We consider the problem of sequencing a set of positive numbers. We try to find the optimal sequence to maximize the variance of its partial sums. The optimal sequence is shown to…
