Log-FSK: A Frequency Modulation for Over-the-Air Computing

no code implementations23 Feb 2024 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

In this study we introduce Logarithmic Frequency Shift Keying (Log-FSK), a novel frequency modulation for over-the-air computing (AirComp).

LoRa Modulation for Split Learning

no code implementations1 Aug 2023 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

In this paper we introduce a task-oriented communication design for split learning (SL) over a communication channel.

ENN: A Neural Network with DCT Adaptive Activation Functions

1 code implementation2 Jul 2023 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

Under a signal processing perspective, in this paper we present Expressive Neural Network (ENN), a novel model in which the non-linear activation functions are modeled using the Discrete Cosine Transform (DCT) and adapted using backpropagation during training.

Frequency Modulation Aggregation for Federated Learning

no code implementations28 Jun 2023 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

In FEEL, edge devices periodically transmit model parameters to the server, which aggregates them to generate a global model.

LoRa-based Over-the-Air Computing for Sat-IoT

no code implementations28 Jun 2023 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

In this paper we propose to use the Long Range (LoRa) modulation for the purpose of estimation in a Sat-IoT scenario.

DCT-based Air Interface Design for Function Computation

no code implementations28 Jun 2023 Marc Martinez-Gost, Ana Pérez-Neira, Miguel Ángel Lagunas

With the integration of communication and computing, it is expected that part of the computing is transferred to the transmitter side.

Over the Air Computing for Satellite Networks in 6G

no code implementations28 Jun 2023 Marc Martinez-Gost, Ana Pérez-Neira

We outline existing gaps in the literature, evincing that current state of the art requires a theoretical framework based on analog and hybrid digital-analog schemes that will boost the evolution of OTA computing.

Edge Computing and Communication for Energy-Efficient Earth Surveillance with LEO Satellites

no code implementations17 Nov 2021 Marc Martinez-Gost, Israel Leyva-Mayorga, Ana Pérez-Neira, Miguel Ángel Vázquez, Beatriz Soret, Marco Moretti

In this paper, we propose an algorithm that allows the satellites to select between computing the tasks at the edge or at a cloud server and to allocate an adequate power for communication.
