Introduction

Arnaldo Spalvieri is a distinguished inventor based in Milan, Italy, known for his significant contributions to communication technologies. With a portfolio comprising 16 patents, Spalvieri has demonstrated remarkable ingenuity in various aspects of multi-antenna communications and signal processing techniques.

Latest Patents

Among his most recent inventions is a patented method and apparatus for multiple antenna communications, which includes a related system and computer program. This innovation outlines a sophisticated method for detecting sequences of multi-level encoded symbols. It involves mapping and modulating the symbols through a modulation scheme characterized by a number of constellation points, categorized into two groups encoded differently. The methodology enables multiple transmitting sources to send the symbols effectively, which are then received as a vector by various receiving elements. The process includes selecting candidate sequences and calculating probability information, leading to the decoding and re-encoding of bits to enhance transmission efficiency.

Another notable patent addresses the reduction of the peak-to-average power ratio (PAR) of a Fourier transform-generated multi-carrier signal within transmission systems. This method aims to diminish the PAR by generating an anti-peak signal that is summed with the modulated signal before transmission. Through these advancements, Spalvieri's inventions are recognized for improving transmission efficiency and reliability.
