该项目涉及计算机存储系统中差错控制码的使用。对于半导体随机存取存储器(RAM)的情况，正在研究在芯片和板级上结合冗余的技术。对于磁记录设备的情况，正在研究在数据的1和0图案的约束下的信道表征、卷积编码和差错控制编码的问题。计算机存储设备的存储容量的一些信息论方面也在考虑之中。

This project is concerned with the use of error control codes in computer memory systems. For the case of semiconductor random access memories (RAM), techniques for incorporating redundancy at both the on-chip and board levels is under investigation. For the case of magnetic recording devices, the issues of channel characterization, convolutional coding, and error control coding under constraints on the 1s and 0s patterns of the data are being studied. Some information theoretic aspects of the storage capacity of computer memory devices is also under consideration.
