FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication and can be used for downlink communication in a time slot-based communication system. The method of preserving bandwidth in a communication system includes expanding a data frame using a first pseudonoise (PN) expander. A broadcast frame is expanded using a second PN expander. A stream of complex data is generated, having a first component and a second component. The data frame is assigned to the first component and the broadcast frame is assigned to the second component. The stream of complex data is transmitted to a tag.
EFFECT: preserving bandwidth during transmission.
