The Takeaway
The Shannon limit has been the 'speed of light' for data since 1948, defining the maximum information possible in a signal. By using a new geometric method to shape signals, this research shows it's possible to send clear messages at power levels once thought to be physically impossible, effectively breaking the speed limit of the internet.
From the abstract
This paper proposes a new method for constructing multidimensional signal constellations (SC), referred to as SCOPT, for high-speed communication systems with enhanced energy efficiency (EE). In contrast to conventional approaches, the proposed method increases the minimum Euclidean distance (MED) between signals by increasing the normalized signal duration, without relying on coding or increasing transmit power.
