Title: The Innovations of Ali M Jalali
Introduction
Ali M Jalali is a notable inventor based in Rennes, France. He has made significant contributions to the field of signal processing, particularly in modulation techniques and Fourier transforms. With a total of 2 patents, his work has had a considerable impact on telecommunications and data transmission.
Latest Patents
One of his latest patents is titled "Multicarrier modulation using weighted prototype functions." This method involves modulating a multicarrier signal by obtaining a set of 2M representative complex coefficients of transmitted data. The process includes calculating 2LM linear combinations to retain the 2M obtained complex coefficients, with coefficients of balancing representing a prototype function g(t). The 2LM coefficients are summed in designated memory areas, forming M samples for transmission over a defined duration.
Another significant patent is the "Method for computing fast Fourier transform and inverse fast Fourier transform." This method calculates the fast Fourier transform or its inverse for a series of N real samples x(n), where N is a power of two. It operates according to a time interleaving algorithm, providing the sample series X(n) in ascending order to index n while utilizing limited calculating storage means. Additionally, it addresses the calculation of the fast Fourier transform for a series of N conjugated complex samples X(n).
