| Summary: | In a constant weight code, each code word contains a constant number of 1's.
If this number is equal to half the length of the code word then the code is called
balanced. These codes find many applications in computer and communication systems
noise reduction in VLSI systems, fault masking in bus lines of VLSI systems,
rejection of the low frequency components in digital communication systems, delay
insensitive communications in asynchronous systems, data transmission in fiber optics,
data storage in optical discs and magnetic tapes, fault tolerant synchronous
circuits, etc. This thesis presents new efficient design methods for constant weight
codes suitable to these applications. The proposed codes require low redundancy
but at the same time have fast and simple encoding/decoding algorithms. === Graduation date: 1997
