Multi-Sensor Accurate Forklift Location and Tracking Simulation in Industrial Indoor Environments
(M D P I AG, 2019-10-12)
[Abstract] Location and tracking needs are becoming more prominent in industrial environments nowadays. Process optimization, traceability or safety are some of the topics where a positioning system can operate to improve ...
Environmental Cross-Validation of NLOS Machine Learning Classification/Mitigation with Low-Cost UWB Positioning Systems
(M D P I AG, 2019-12-10)
[Abstract] Indoor positioning systems based on radio frequency inherently present multipath-related phenomena. This causes ranging systems such as ultra-wideband (UWB) to lose accuracy when detecting secondary propagation ...
FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems
(M D P I AG, 2020-02-10)
[Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...
A Real-Time Implementation of the Mobile WiMAX ARQ and Physical Layer

Design of Linear Precoders for Correlated Sources in MIMO Multiple Access Channels
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: This paper focuses on distributed linear precoding when users transmit correlated information over a fading multiple-input and multiple-output multiple access channel. The precoders are optimized in order to ...
Transmission of Spatio-Temporal Correlated Sources Over Fading Multiple Access Channels With DQLC Mappings
(Institute of Electrical and Electronics Engineers, 2019-08)
[Abstract]: The design of zero-delay Joint Source-Channel Coding (JSCC) schemes for the transmission of correlated information over fading Multiple Access Channels (MACs) is an interesting problem for many communication ...
Analog Transmission of Spatio-Temporal Correlated Sources Over MAC With Modulo Mappings
(Institute of Electrical and Electronics Engineers, 2018-05)
[Abstract]: Modulo mappings is an appealing scheme for the analog transmission of spatially correlated discrete-time analog source symbols over multiple access channels. In this letter, we show that the modulo mappings are ...
Lattice-Based Analog Mappings for Low-Latency Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers, 2023-10-01)
[Abstract]: We consider the transmission of spatially correlated analog information in a wireless sensor network (WSN) through fading single-input and multiple-output (SIMO) multiple access channels (MACs) with low-latency ...
Transmission of Analog Information Over the Multiple Access Relay Channel Using Zero-Delay Non-Linear Mappings
(Institute of Electrical and Electronics Engineers, 2019-04-04)
[Abstract]: We consider the zero-delay encoding of discrete-time analog information over the Multiple Access Relay Channel (MARC) using non-linear mapping functions. On the one hand, zero-delay non-linear mappings are ...
