Title:

A SYNERGETIC TRANSMITTING SYSTEM FOR DIGITAL BROADCAST SFN AND METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2007/134486

Kind Code:

A1

Abstract:

A synergetic transmitting system for digital broadcast SFN and method thereof are disclosed. The synergetic transmitting system includes a double layer synergetic transmitting structure having the same frequency, which includes: a main transmitting layer including some main transmitters having the same transmitting frequency; and an auxiliary transmitting layer including some auxiliary transmitters having the same transmitting frequency, wherein frequency of electromagnetic wave transmitted from the main transmitter is the same as that transmitted from the auxiliary transmitter, information symbols carried by them are the same, and they have synchronization relation meeting requirement of avoiding disturbance between symbols. The diploid interlamination synergetic transmitting structure is formed by overlapping another double layer synergetic transmitting structure. And a synchronization method of the double layer synergetic transmitting structure and a determination method of power transmitted from them are disclosed. By using the invention, frequency spectrum efficiency, overlay quality and support capability for mobility of digital broadcast system are improved, and high compatibility may be held with existing digital broadcast system.
