He has made significant contributions to the field of communication systems, particularly in digital modulation techniques. With a total of 2 patents, his work is recognized for its innovative approach to enhancing communication efficiency.
Latest Patents
Martinez Vicente's latest patents include a groundbreaking method for coded digital modulation in communication systems. This new class of 16-ary Amplitude and Phase Shift Keying (APSK) coded modulations, known as double-ring APSK modulation, utilizes an amplitude and phase shift keying constellation. The digital signals are strategically placed 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 modulation scheme is designed to work effectively 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 inherent 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.
