1. A method for conserving bandwidth in a communication system, the method comprising:
- spreading a data frame using a first pseudo-noise (PN) spreader;
spreading a broadcast frame using a second PN spreader;
generating a complex data stream having a first component and a second component, wherein the data frame is assigned to the first component and the broadcast frame is assigned to the second component, and wherein the first component comprises a real component of the complex data stream and the second component comprises an imaginary component of the complex data stream; and
transmitting the complex data stream to a tag.

Abstract
A method for conserving bandwidth in a communication system includes spreading a data frame using a first pseudo-noise (PN) spreader. A broadcast frame is spread using a second PN spreader. A complex data stream having a first component and a second component is generated. The data frame is assigned to the first component and the broadcast frame is assigned to the second component. The complex data stream is transmitted to a tag.
