Due to the exponential growth of Internet usage and inefficiency of the traditional modulations, the capacity of the current optical fiber networks is not sufficient for future Internet demands. As a result, increasing the capacity of the fiber networks is of great importance. Since most of the...

This document presents a case study in the as-yet unexplored avenue of exploiting running digital sum (RDS) statistics to achieve reduced error rates in the detection of balanced guided scrambling (GS) coded sequences. As demonstrated in this research, balanced GS codes are a good candidate for...

Traditionally, constrained sequence coding has been employed exclusively in codes using binary or multilevel signalling. This thesis extends the procedure for constructing DC-free constrained sequence codes to alphabets that use signalling constellations with complex-valued symbols. In...

The use of variable-length codes to construct capacity approaching constrained sequence codes is examined. Constrained sequence codes are commonly used for digital storage and transmission, but have historically been implemented using block codes. A new technique is developed for constructing...
