Nicholas William Whinnett, Kevin Michael Laird: Method and system for generating a complex pseudonoise sequence for processing a code division multiple access signal. Motorola, L Bruce Terry, June 12, 2001: US06246697 (9 worldwide citation)

In a wireless communication system, a chip time is selected in a complex pseudonoise (PN) sequence generator. For a next chip time following the selected chip time, a phase difference between a previous complex PN chip and a next complex PN chip is restricted to a preselected phase angle. In one emb ...
