Lossless Data Compression for Communication Systems Based on Optical Frequency Discriminator

Abstract

We propose a novel lossless data compression scheme for a high-speed communication system. Previous works have usually addressed the data compression issue within an identical plane by pure mathematical processing. Here, we convert the binary information into a novel sparse expression form in which the information is divided into two parts: time sequence information and difference value information, which are sent to the destination by two distinct means of transmission. Furthermore, by a deliberately designed symbol called the semantic wavelength, we can select a better compression scheme among candidates. It is expected that our scheme can reach 13.8% data compression ratio.
