ABSTRACT:
The present invention relates to a digital communication architecture based upon the concept of time encoding. In one aspect, systems provide time-encoding-based digital communication, the systems comprising a transmitter, a communication channel, and a receiver. In another aspect, methods for digital communication comprise time encoding digital input data and then transmitting the resultant asynchronous pulse signal to a receiver that converts the asynchronous pulse signal back into digital symbols. Methods of providing a digital communication link can include (i) providing digital symbols, (ii) time encoding the digital symbols to generate asynchronous pulse signals, (iii) communicating switching times of the signals to a receiver, and (iv) digitizing in parallel and reconstructing the digital symbols. The methods and systems of the invention can utilize existing chip-scale circuit technologies and can be characterized by link capacities of 50 Gbit/sec, 100 Gbit/sec, 200 Gbit/sec, or higher.
