Title: Inventions and Achievements of Chadi Abou Rjeily
Introduction
Chadi Abou Rjeily, an esteemed inventor hailing from Byblos, Lebanon, has made significant contributions to the field of technology through his innovative inventions. With an impressive portfolio of 14 patents, his work predominantly focuses on advancing communication systems, particularly in the areas of modulation and signal processing.
Latest Patents
Chadi Abou Rjeily's latest patents include:
1. **Space-time coding method using a partitioned position modulation alphabet** - This invention pertains to a space-time coding method designed for a Multiple-Input Multiple-Output Ultra Wideband (MIMO-UWB) system with P antennas. It utilizes information symbols from an M-PPM, where M is a multiple of P. The modulation alphabet is strategically partitioned into P sub-alphabets, corresponding to successive modulation positions. This method enhances the binary rate of the system by forcing information symbols into specific sub-alphabets.
2. **Maximum likelihood decoder for pulse position modulation multi-source system** - In this innovative approach, P pulse position modulation (PPM) symbols are transmitted simultaneously and represented as points in a modulation product constellation within a signal space of dimension MP. The process incorporates sphere decoding, where the signal received is transformed into a representative point, and the closest point within a designated sphere of quadratic radius is determined. This technique includes zero-forcing decision feedback equalization (ZF-DFE) and systematically evaluates contributions from modulation symbols across multiple layers, optimizing the selection process for the lowest contribution until completion across all layers.
