MIMO relaying with linear processing for multiuser transmission in fixed relay networks
- IEEE TRANS. SIGNAL PROCESSING
, 2006
"... In this paper, a novel relaying strategy that uses multiple input multiple output (MIMO) fixed relays with linear processing to support multiuser transmission in cellular networks is proposed. The fixed relay processes the received signal with linear operations and forwards the processed signal to m ..."

Joint Virtual MIMO and Network Coding Scheme with Superposition ARQ in Two-way Relay System
, 2013
"... A new two-way transmission protocol termed VMNC-SARQ (Virtual MIMO Network Coding with Superposition ARQ) was proposed in this paper, which could improve throughput efficiency of DF (Decode-and Forward) relay network significantly. In first step, two single-antenna nodes send messages to the double- ..."

Feedback Constraints for Adaptive Transmission -- Limits of AMC and MIMO for frequency division duplex systems
- IEEE SIGNAL PROCESSING MAGAZINE
, 2007
"... The growth of wireless networks in recent years coupled with applications demanding high data rates underscores the fact that the communication system is bandwidthand power-limited. Therefore, an efficient utilization of the radio spectrum is of paramount importance, particularly in developing ban ..."

bandwidth- and power-efficient communication systems. Adaptive transmission has emerged as a viable approach to boost transmission rates in a communication system. Adaptive transmission refers to signaling strategies that adapt some combination of the modulation, transmit power, and coding scheme
A cross-layer TCP modelling framework for MIMO wireless systems
- IEEE Trans. Wireless Commun
, 2006
"... Abstract — We propose a general framework based in the Gilbert model for cross-layer analysis of TCP and UDP over MIMO wireless systems. Our framework takes into consideration diverse system characteristics often difficult to express as a Gilbert model such as fading, space-time transmission schemes ..."

Tomlinson-Harashima Precoding with Adaptive Modulation for Fixed Relay Networks
"... Abstract — In this paper, a relaying strategy that uses multiple input multiple output (MIMO) fixed relays with linear processing for multiuser transmission in cellular networks is proposed. This approach applies to the two hop relaying scenario for coverage enhancement, where the base station trans ..."

Analog Joint Source-Channel Coding for OFDM Systems
"... Abstract—Recently, analog Joint Source-Channel Coding (JSCC) has been shown to approach the optimal distortion-cost trade-off when transmitting over AWGN channels. In this work we consider analog JSCC over frequency-selective channels using Orthogonal Frequency Division Multiplexing (OFDM) modula-ti ..."

We show that the three analog JSCC transmission strategies approach the optimal distortion-cost trade-off although much better performance is obtained with the adaptive coding with precoding method, specially in Multiple Input Multiple Output
Multi-user MIMOOFDM cell throughput under real-world propagation conditions
- IEEE Proceedings of the Vehicular Technology Conference
"... Abstract — In recent years, an innumerable number of papers has been published on MIMO (multiple input multiple output) systems. The original and most of the current work deals with a single link between a multi-element antenna (MEA) transmitter and a MEA receiver. However, link-level capacity gain ..."
