Title: Albert Guillen I Fabregas: Innovator in Communication Systems
Introduction
Albert Guillen I Fabregas is a notable inventor based in Barcelona, Spain. He has made significant contributions to the field of communication systems, particularly through his innovative patent. His work focuses on enhancing the efficiency and performance of digital modulation methods.
Latest Patents
Albert holds a patent for a "Coded digital modulation method for communication system." This invention introduces a new class of 16-ary Amplitude and Phase Shift Keying (APSK) coded modulations, known as double-ring APSK modulation. This method utilizes an amplitude and phase shift keying constellation where the digital signals are encoded on two concentric rings of equally spaced signal points. The APSK constellation parameters are optimized to pre-compensate for the impact of non-linearities. This new modulation scheme is particularly effective when used with various coding schemes. It has been demonstrated that, for the same coding scheme, pre-distorted double-ring APSK modulation significantly outperforms classical 16-QAM and 16-PSK over typical satellite channels. This is due to its intrinsic robustness against the high power amplifier non-linear characteristics. The proposed coded modulation scheme offers considerable performance advantages for future satellite multimedia and broadcasting systems.
