In this work, a study has been carried out on the behaviour of MFCCs when distortion is applied to a signal. Subsequently, the conclusions drawn from the study have been used to customise an LSTM network to allow the implementation of a module that i

Wi-Fi is the facto standard protocol for most indoor personal communication devices. Despite this, its usage in IoT solutions is limited, mainly due to the high cost and elevated power consumption of Wi-Fi transceivers. The power consumption of Wi-Fi

In this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different frequencies involved in FSK

There exists today an increasing demand for wireless devices which require low cost and minimum power consumption radiofrequency front-ends. Precisely, these are two remarkable characteristics of the superregenerative receiver (SR). In this thesis, w

In this paper we describe a superregenerative (SR) MSK receiver able to operate in a burst-mode framework where synchronization is required for each packet. The receiver is based on an SR oscillator which provides samples of the incoming instantaneou
