On the Capacity Region and the Generalized Degrees of Freedom Region for the MIMO Interference Channel with Feedback
Mehdi Ashraphijuo, Vaneet Aggarwal, Xiaodong Wang
In this paper, we study the effect of feedback on two-user MIMO interference channels. The capacity region of MIMO interference channels with feedback is characterized within a con…
Sequential Decentralized Parameter Estimation under Randomly Observed Fisher Information
Yasin Yilmaz, Xiaodong Wang
We consider the problem of decentralized estimation using wireless sensor networks. Specifically, we propose a novel framework based on level-triggered sampling, a non-uniform samp…
Degrees of Freedom for MIMO Two-Way X Relay Channel
Zhengzheng Xiang, Meixia Tao, Jianhua Mo +1
We study the degrees of freedom (DOF) of a multiple-input multiple-output (MIMO) two-way X relay channel, where there are two groups of source nodes and one relay node, each equipp…
Pricing-based Distributed Downlink Beamforming in Multi-Cell OFDMA Networks
Weiqiang Xu, Xiaodong Wang
We address the problem of downlink beamforming for mitigating the co-channel interference in multi-cell OFDMA networks. Based on the network utility maximization framework, we form…
Adaptive Sensing of Congested Spectrum Bands
Ali Tajer, Rui M. Castro, Xiaodong Wang
Cognitive radios process their sensed information collectively in order to opportunistically identify and access under-utilized spectrum segments (spectrum holes). Due to the trans…
Channel-aware Decentralized Detection via Level-triggered Sampling
Yasin Yilmaz, George V. Moustakides, Xiaodong Wang
We consider decentralized detection through distributed sensors that perform level-triggered sampling and communicate with a fusion center via noisy channels. Each sensor computes…
