Leakage-Based Hybrid Transceiver Design for Millimeter Wave Multi-User Interference ChannelAuthors: Jagyasi Deepa,Ubaidulla P Conference: 2017 IEEE Global Communications Conference(GLOBECOM) Date: 2017-12-04 Report no: IIIT/TR/2017/126 AbstractMillimeter wave (mmWave) communication is en- visioned as a potential technology for next generation mobile communication as it can offer multi-gigabit-per-second data rate and a huge unlicensed spectrum. In this paper, we present a signal leakage-based low-complexity hybrid analog-digital transceiver design for a mmWave communication system operating in a K-user MIMO interference channel. Owing to higher cost and power consumption of components at mmWave frequencies, optimal system design with reduced hardware and computational complexity is critical to make the commercial use of mmWave communication viable. We achieve reduced hardware complexity of the proposed design by employing sparse approximation techniques for large antenna array. The proposed design is based on the maximization of signal-to-leakage-plus-noise ratio (SLNR) for all users. This leads to the reduced computational complexity of the overall system. Numerical results comparing the proposed design with existing iterative solution demonstrate that it can achieve comparable performance with reduced hardware and computational complexity. Performance of the proposed design with various dictionaries considered for beamforming has also been compared and illustrated in the simulation results. Keywords mmWave communication, sparse signal processing, hybrid transceiver, orthogonal matching pursuit, 5G. Full paper: pdf Centre for Communications |
