This work presents a fully digital implementation of an audio front-end for portable applications developed in a low-power perspective.Such platform acquires audio samples through a four digital Pulse Digital Modulation (PDM) microphones array andimplements two-channel…
Voice Activity Detectors (VADs) are used to enhance performances and to reduce the activation rate of speech recognition and key-word spotting applications. The last aspect is crucial for portable applications because it allows to save…
Nowadays Voice User Interfaces (VUIs) have become popular thanks to their easiness of use that makes them accessible to the elderly and people with disability. Nevertheless, their use in embedded systems for the realization of…
Recursive Systematic Convolutional (RSC) codes are the building blocks of the modern communication systems. In this paper we propose a new analytical model to manipulate the modulo-2 algebraic operations and a finite state machine model …
Several humanoid robots will require to navigate in unsafe and unstructured environments, such as those after a disaster, for human assistance and support. To achieve this, humanoids require to construct in real-time, accurate maps of…
