Minimum Polarized Distance Codes
IBM Journal of Research and Development, 1961The choice of a code for a given application is influenced by many factors, such as economics, compatibility, and reliability. This paper is concerned solely with the reliability of codes, and shows how, for a given number of bits per character and a given minimum distance, the probability of undetected error in an asymmetric channel may be reduced by ...

A variation on channel polarization coding is presented. In standard channel polarization coding the code length is an integral power of two. Our scheme allows modifying the code at the graph definition level to an arbitrary blocklength. Working at the graph definition level of the code enables the utilization of the newly produced codes for every ...

Abstract : The POLAR code was written to model charging by large spacecraft in low, polar orbit. This report documents comparisons of POLAR code calculations with flight experiments. Calculations of the plasma wake behind the Shuttle Orbiter are compared with the situ measurements of Murphy et al. 1989. Calculations of the charging of DMSP-7, performed

An optimization algorithm for finding a shortening pattern and a set of frozen symbols for polar codes is proposed. The structure of polar codes is exploited to eliminate many equivalent shortening patterns, thus reducing the search space. A reduced-complexity suboptimal algorithm is proposed for finding shortening patterns for long polar codes ...
