Abstract :
We will discuss the generation of DC-free runlength-limited (DCRLL) sequences. We propose to employ standard RLL codes, where DC-control is effectuated by multiplexing the source data or the encoded data with DC-control bits. The DC-control bits offer the degree of freedom required to shape to spectrum. It is shown that a new technique, called parity preserving assignment, will offer great benefits over other constructions
