Physical layer signaling system based on wireless digital multimedia broadcasting

Abstract

The invention provides a physical layer signaling system based on wireless digital multimedia broadcasting. The system comprises an independent signaling module and an accompanying signaling module; the independent signaling module comprises a leading signaling unit, a physical frame signaling unit and a logical frame signaling unit, wherein the leading signaling unit is used for identifying the type of a physical frame, responding emergency broadcast information and obtaining attribute information of the physical frame, the physical frame signaling unit is used for acquiring the attribute information of the physical frame so as to assist in analyzing the physical frame and divided into a conventional signaling mode of physical frame signaling and a simplified signaling mode of physical frame signaling, and the logical frame signaling unit is used for acquiring attribute information of a transmission channel in the logical frame and comprises logical frame configuration signaling, logical frame dynamic signaling and logical frame extension signaling; the accompanying signaling module comprises a first accompanying signaling module and a second accompanying signaling unit. The physical layer signaling system based on wireless digital multimedia broadcasting functionally supports different transmission parameters for different transmission channels, receives quality services of different grades, rapidly receives the emergency broadcast information and assists streaming transmission, and rapid scanning, power saving and signaling overhead saving are all achieved in performance.

Description

Technical field [0001] The invention belongs to the technical field of wireless communication, and particularly relates to a physical layer signaling system based on wireless digital multimedia broadcasting.
