Spectral and Energy Spectral Efficiency Optimization of Joint Transmit and Receive Beamforming Based Multi-Relay MIMO-OFDMA Cellular Networks
Kent Tsz Kan Cheung, Shaoshi Yang, Lajos Hanzo
We first conceive a novel transmission protocol for a multi-relay multiple-input--multiple-output orthogonal frequency-division multiple-access (MIMO-OFDMA) cellular network based…
An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems
Anzhong Hu, Tiejun Lv, Hui Gao +2
In this paper, an approach of estimating signal parameters via rotational invariance technique (ESPRIT) is proposed for two-dimensional (2-D) localization of incoherently distribut…
Limited Feedback-Based Interference Alignment for Interfering Multi-Access Channels
Hui Gao, Tiejun Lv, Di Fang +2
A limited feedback-based interference alignment (IA) scheme is proposed for the interfering multi-access channel (IMAC). By employing a novel performance-oriented quantization stra…
Maximizing Energy-Efficiency in Multi-Relay OFDMA Cellular Networks
Kent Tsz Kan Cheung, Shaoshi Yang, Lajos Hanzo
This contribution presents a method of obtaining the optimal power and subcarrier allocations that maximize the energy-efficiency (EE) of a multi-user, multi-relay, orthogonal freq…
