Title:
ブロードキャスト測位信号の生成方法、測位方法及び装置
Document Type and Number:
Japanese Patent JP5714113
Kind Code:
B2
Abstract:
The present invention, pertaining to the field of mobile broadcast television technologies, discloses a method and apparatus for generating a broadcast positioning signal, and a positioning method. The method for generating a broadcast positioning signal includes: receiving a data stream, performing forward error correction coding and orthogonal frequency-division multiplexing (OFDM) modulation on the data stream, and generating an OFDM signal and a first spread spectrum signal; performing spread spectrum modulation on preset message bit information according to the first spread spectrum signal to generate a spread spectrum modulation signal; and inserting one or more than one spread spectrum modulation signal and one or more than one first spread spectrum signal in a transmitter identifier signal and a first synchronization signal in each time slot of the OFDM signal, to generate a broadcast positioning signal. According to the present invention, a broadcast positioning signal is generated by inserting a spread spectrum signal and a first spread spectrum signal in an OFDM signal, and a receiver is positioned according to broadcast positioning signals from at least three different senders.
