Abstract
The invention describes a method and device for designing a set of codewords, which have good properties for use in communication systems. These codeword sets are useful because they provide advantages to a communication system that uses them in that they result in lower error rates in the receiver. The method for designing the codes is to take a good set of codes with perfect periodic autocorrelation and manipulate it so as to transform it into a better code-set, for example a code-set with higher mean Golay merit factor, lower spectral peak to average ratio and lower mean cross correlation.
