Patent number: 7269126Abstract: A method for constructing orthogonal codes of length N for use in a network utilizing quasi-synchronous code division multiple access combined with time division duplexing. The method determines the balanced vectors of length N, being all possible cross-correlation vectors resulting from zero cross-correlation of codes of length N. An arbitrary code of length N is utilized, and a bitwise XOR-ing is performed with all the balanced vectors to produce a set of codes with which the arbitrary code is orthogonal. A bitwise XOR-ing of the original balanced vectors is performed and the code is added to a set of orthogonal codes if the result of the bitwise XOR-ing of the original balanced vectors is balanced. The method is repeated until the set of orthogonal codes is complete.Type: GrantFiled: September 15, 2003Date of Patent: September 11, 2007Assignee: Agilent Technologies, Inc.Inventors: Jan Mennekens, Carl Mertens, Lieven Philips, Jurgen Vandermot, Jan Vanhoof
