Title: Raphaël Le Bidan: Receiver and Signal-Processing Innovation.

Introduction

Raphaël Le Bidan is an inventor associated with Plouzané, France, and Institut Mines-Telecom. His work includes a patent for a receiver and transceiver system that addresses signal detection when transmitted symbols have a non-zero expected value.

Latest Patents

Le Bidan is credited with 1 patent: “Receiver, transceiver system and associated receiving method.” The invention describes a receiver with a sampler that provides one or more samples for each received symbol, an equalizer that estimates each symbol using a linear combination of those samples, and a decision module that selects the closest symbol from a predefined alphabet. Because the alphabet is decentered, the transmitted symbols have a non-zero predefined expectation. The equalizer adds a non-zero scalar component to the sample combination to compensate, at least partially, for that decentering.

Career Highlights

The patent reflects Le Bidan’s work on receiver design and signal processing, particularly the estimation and detection of symbols in communication systems. The available information associates him with Institut Mines-Telecom.

Collaborations

Institut Mines-Telecom is the organization identified in the provided information about Le Bidan. The available details do not specify additional collaborators or the organization’s precise role in the patent.

Conclusion

Raphaël Le Bidan’s patented receiver approach combines sampling, equalization, and symbol selection to address decentered signal alphabets.
