GNSS is capable of providing high-precision and drift-free attitude information. The traditional attitude determination methods based on the baseline vector and carrier phase measurement process attitude determination estimation and ambiguity resolution sequentially. And the redundant measurements from multi-baselines have not been fully utilized. A GNSS measurements based attitude determination method...
This paper investigates secrecy and connection performance for uplink transmission in a two-tier heterogeneous network with non-uniformly deployed low- power small base stations (BSs). All BSs and the eavesdropper are equipped with multiple antennas. We propose an aggregate interference approximation approach to characterize the statistics of interference generated by users associated with small BSs...
Today's mobile network traffic is growing in an exponential way, the current cellular system structure has been changed due to the lack of spectrum and the other factors, such as the difficulty of property coordination and the higher rent expense. In this paper, several interference management techniques in HetNet are studied, and the effects of the PCI program on the LTE coverage is analyzed. This...
In this paper, the low information-exchange and robust precoding design for distributed antenna systems is investigated, which is of great importance for the new mobile network architecture namely cloud radio access networks (C-RAN). Relying on an interesting low complexity decomposition algorithm, a distributed robust linear minimum mean-square-error (LMMSE) precoding algorithm is proposed. Exploiting...
Cloud radio access network (C-RAN) is a new concept of network architecture, which brings a technical revolution into the wireless communication market and leads to some kind of all new mode of the future wireless communications. In this paper the clustering algorithm based on multi-objective optimization is investigated. The proposed algorithm aims at maximizing the throughput contribution of the...
Radio Frequency Identification (RFID) is a key technology in logistic management, object tracking, object locating, patient supervision, and many other applications. The design and deployment of the RFID system in real application is challenging due to the complexity of the factors involved. In this paper, a novel systematic scheme is proposed to provide practical guidance on the design of RFID systems...
