Introduction

Sorin Adrian Barbulescu is an accomplished inventor based in Adelaide, Australia. With a strong focus on communication technologies, he has been granted five patents that showcase his innovative contributions to the field.

Latest Patents

One of Sorin's latest inventions is a "Multiuser Communications System," which includes multiple transmitters and a multiuser receiver designed to detect various transmissions through iterative soft interference cancellation. This system features an initial acquisition module and a single-user decoder module, allowing the multiuser receiver to successfully acquire and subtract known user signals from the residual signal. The process is iteratively refined until no new users are detected or a predetermined stopping criterion is satisfied. To enhance the receiver's acquisition capabilities, the transmitters insert discrete tones, enabling the receiver to gather initial estimates of essential parameters such as frequency, time, gain, and phase offsets for each user. Additionally, as each iteration progresses, the receiver improves its estimates to optimize cancellation quality and calculates time-varying SINR estimates for each user. This innovative multiuser receiver can be satellite-based, utilize distributed processing, or handle simultaneous user processing.

Another of Sorin's patents involves a "Communication System and Method," which outlines a comprehensive structure that facilitates efficient data transfer. This system comprises a user node for receiving data from a remote application program, alongside a network of geographically distributed gateway nodes and access nodes that manage the transmission of message data. The hub communicates effectively with these gateway nodes to ensure smooth communication of the message data to a central application.
