Title: Efficient spreader for spread spectrum communication systems

Abstract: A spreading system and method for CDMA applications that requires fewer integer multiplications. User data is spread using real or complex integer based spreading codes of length SF to SF.sub.max chips. At least one of the codes is of the form j.sup.nv[n] where v[n] is a spreading code. The invention provides increased user separation using a plurality of spreading codes.
