We present ATHOME, an Automatic Tunable wireless charging framework for smart low-power devices in current and future HOME. ATHOME automatically tunes the charging power of multiple stationary wireless chargers to provide enough energy that can continuously power up smart devices with varying working power profiles, while minimizing the total charging power to reduce energy cost. To reach this goal,...
Distributed antenna system (DAS) is one of the promising techniques for next generation wireless communication. In this paper, we firstly present a relatively efficient sphere decoding algorithm (SDA) that performs exact maximum-likelihood (ML) decoding for distributed antenna systems, which does not necessarily require that the number of receive antennas should be no less than that of transmit antennas...
We propose a subspace-based blind channel estimation method for distributed multi-input single-output systems, where one side of the link constitutes a largely spaced antenna array. The proposed approach does not necessarily require that the number of receive antennas should be no less than that of transmit antennas and reduces the computational complexity. Sufficient identifiability conditions are...
