GetSensorData: An extensible Android-based application for multi-sensor data re...
Gutierrez, Juan D.; Jimenez, Antonio R.; Seco, Fernando; Alvarez, Fernando J.; Aguilera, Teodoro; Torres-Sospedra, Joaquín; Melchor, FranSmartphones are powerful tools with extensive sensorization that can provide useful information in research or everyday life applications. This information can be obtained from the device's built-in sensors or through other external sensors connected physically via USB or wirelessly via Bluetooth or WiFi. This paper presents the GetSensorData application that provides an open-source, flexible and extensible fra...
High Energy OFDM Pulse Design Algorithm for Acoustic ToF Ranging and Localization
Albuquerque, Daniel; Vieira, José; Lopes, Sérgio; Aguilera, Teodoro; Álvarez, FernandoThis paper proposes an algorithm to design band-limited Orthogonal Frequency Division Multiplexing (OFDM) pulses for accurate time-of-flight ranging in acoustic-based localization systems. The proposed algorithm is capable to generate OFDM pulses with higher energy when compared with other common pulse design approaches with similar characteristics. The results attained have shown that it is possible to design ...
