Abstract  Abstract

Mobile unit for use in a spread spectrum communication system, comprising: means (604) for generating an orthogonal sequence signal corresponding to a selected sequence of a plurality of orthogonal binary sequences; means (614, 616) for generating a PN pseudo noise signal (PNI, PNQ) corresponding to a predetermined binary PN sequence; and means (610, 612) for combining said orthogonal sequence signal, and said PN signal and for providing a resulting signal, characterized in that said means (604) for generating an orthogonal sequence signal are configured to receive an input signal and convert sequential portions of said input signal in respective sequences of said orthogonal binary sequences selected from said plurality of orthogonal binary sequences according to a value of said respective input signal portion; the default PN binary sequence is a sequence assigned to all mobile units in the system; and means (606, 608) are provided to generate a single additional predetermined PN signal (PNU) to the mobile unit and combine said orthogonal sequence signal with said additional PN signal to produce a corresponding spread signal of the mobile unit.
