This project deals with the properties and applications of balanced codes. In a balanced code, each code word contains equal number of 1's and O's. These codes find many applications in computer and communication systems such as noise reduction in VLSI systems, fault masking in bus lines of VLSI systems, delay insensitive communications in asynchronous systems, data transmission in fiber optics, data storage in optical discs and magnetic tapes, and fault tolerant synchronous circuits. The objective of this research is to develop design methods for balanced codes suitable to these applications. Our aim is to design codes which require low redundancy but at the same time have fast and simple encoding/decoding algorithms. Other topics such as error correcting balanced codes, asymmetric error correcting and detecting codes applicable to the above mentioned applications will also be investigated.

这个项目涉及平衡码的性质和应用。 在平衡码中，每个码字包含相等数量的1和0。 这些码在计算机和通信系统中有许多应用，如VLSI系统中的噪声降低、VLSI系统总线中的故障掩蔽、异步系统中的延迟不敏感通信、光纤中的数据传输、光盘和磁带中的数据存储以及容错同步电路。 本研究的目的是开发适合这些应用的平衡码的设计方法。 我们的目标是设计代码，需要低冗余，但在同一时间有快速和简单的编码/解码算法。 其他主题，如纠错平衡码，非对称纠错和检测码适用于上述应用程序也将进行研究。
