Introduction

Pierre Siohan is a prominent inventor based in Rennes, France. He has made significant contributions to the field of telecommunications, particularly in the area of modulation techniques. With a total of 18 patents to his name, Siohan's work has had a substantial impact on the efficiency and effectiveness of data transmission.

Latest Patents

One of Siohan's latest patents is focused on the precompensation of interference induced by an OFDM/OQAM modulation that operates faster than Nyquist. This invention addresses the challenges of inter-symbol interference (ISI) and sub-carrier interference (ICI) that arise when compressing faster-than-Nyquist OFDM pulses over time. By estimating ISI and ICI at the transmitter, Siohan's method allows for the precoding of symbols to cancel out these interferences during transmission and reception. Another notable patent involves a method for transmitting complex data symbols through a multiple carrier signal. This method includes several steps, such as converting complex data symbols from the frequency domain to the time domain, cyclic repetition, filtering, and summation to produce time samples.
