Properties of even length Barker codes and specific polyphase codes with Barker type autocorrelation functions
Abstract
Properties of even-length Barker codes, if they exist, are derived. The analysis leads to the analysis of polyphase codes. Similar properties are derived for specific types of polyphase codes, with Barker type autocorrelation functions. The analysis is done in the time and frequency domains (including linear algebra and Z transform treatments), and suggests a procedure to search for codes with Barker type autocorrelation functions. The search problem is reduced by using the properties of such codes.
