Summary We can accurately estimate which way a mobile phone user is facing regardless of the position of their phone or its orientation. Knowing which way a user is facing can provide valuable information for the provision of mobile services and applications. The proposed technology utilises inertial sensors that are readily available in mobile...

Mobile Devices Spectrum Sensing

Summary Spectrum sensing is a signal-processing technique which autonomously exploits local vacant frequency bands. The architecture allows simultaneous search over multiple frequency sub-bands. Benefits High reliability and spectral efficiency (high accuracy and sub-band level sensing). 95% in probability of detection (PD) and 5%...

Method for processing RF signals for receiving and transmission

Summary Radio frequency (RF) radiation is often used in the communication fields for signal receiving and transmission. There is however a lot of interference which needs to be suppressed and the current techniques used for this are expensive and often hard to integrate in to Integrated Circuits (IC's). Integrated circuits are used in almost all...
