Title: Innovations of Hikmet Sari

Introduction

Hikmet Sari is a notable inventor based in Créteil, France. He has made significant contributions to the field of radiocommunication systems, holding a total of 17 patents. His work focuses on enhancing communication methods and increasing network capacities.

Latest Patents

One of Hikmet Sari's latest patents is a transmission method for use in a multiple access radiocommunication system. This method addresses the challenge of accommodating a number of users that exceeds the available transmission resources. By allowing at least two users to share a transmission resource at a given time, the method aims to evenly distribute the deterioration of the signal-to-noise ratio among users. Additionally, the signals corresponding to users sharing the same resource are differentiated based on their transmit levels to further reduce signal degradation.

Another significant patent involves a method of increasing the capacity of a Code Division Multiple Access (CDMA) network. This invention allows for the simultaneous setup of multiple calls between a central unit and remote units. By synthesizing and subtracting interference caused by group calls, the method enhances the overall capacity of the network.
