Using the MIMO-SDM technique, Bell Labs aims to overcome the capacity limitations imposed by the non-linear Shannon limit
on current optical fiber.
The purely digital multifunctional receiver is targeted for end-applications such as combat-radio and radio-relay, providing robust communication at lowsignalto-noise ratio with performance approaching the Shannon limit
(Fagoonee & Honary, 2004).

In the lab, we're there" at the Shannon limit
, says Robert McEliece, a coding theorist at the California Institute of Technology in Pasadena.
It is well known that the capacity of a communication channel is constrained by the Shannon limit
This achievement will have increasing value as transmission technology approaches the 'non-linear Shannon limit
709 standard, nearly reaching the theoretical maximum defined by the Shannon Limit
Soft Decoded Multi-bit/cell Limits and Hard Decoded 1bit/cell Limit vs, Shannon Limit
In recent years, worries have arisen regarding the theoretical capacity limits for fiber-optic technology, and several methods have been proposed to overcome the barrier posed by the nonlinear Shannon limit
These function as an error correction method to ensure the optimum transfer of communications with performance levels approaching the theoretical Shannon limit
(maximum information transfer rate over a noisy channel).
