Abstract
A method of generating a waveform with a plurality of orthogonal PN codes for use in a communications network utilizing quasi-synchronous code division multiple access. The orthogonal PN codes modulate multiple data streams together with a non-orthogonal PN code having desirable auto-correlation properties. The result is a complex signal with time-aligned PN codes.
