Embodiment Construction

[0022] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0023] A method to achieve transmitter identification such as figure 2 As shown, the method includes:

[0024] An identification rule is agreed between the transmitter and the receiver; the identification rule can be agreed upon by generating several random identification sequences in the frequency domain and storing them in a random sequence table.

[0025] Then assign a random identification sequence to each transmitter according to an agreed identification rule; for example, assign a random identification sequence to each transmitter according to the random sequence table.

[0026] If ordinary digital IDs are used, such as one-to-one correspondence between integers and transmitters, the reliability is poor, and the identification accuracy of transmitters is not high, but after using random identification signals, the peak-to-avera...

Abstract

A method for realizing transmitter identification, which is applied in the field of mobile digital multimedia broadcasting, is characterized in that the method includes: agreeing on identification rules between the transmitter and receiver or system maintenance equipment; The machine specifies a random identification sequence; at the transmitter side: when transmitting, the transmitter converts the random identification sequence into a random identification signal and inserts it into the transmission signal before transmitting. After adopting the technical solution of the present invention, users or system maintainers can identify transmitters in different regions and different transmitters in the same region according to the identification signals emitted by the transmitters, so that network testing can be performed conveniently and faulty transmitters can be diagnosed effectively ; In addition, the technical solution of the present invention can also realize the reliable transmission of the identification signal, and occupy limited system bandwidth, thereby improving the transmission efficiency.

Description

technical field [0001] The invention relates to the field of mobile digital multimedia broadcasting, in particular to a system and method for transmitter identification in mobile digital multimedia broadcasting. Background technique [0002] Mobile digital multimedia broadcasting has the characteristics of large coverage and large signal transmission volume, and its information dissemination is point-to-face. Single frequency network is one of the main ways to expand the coverage of digital broadcasting at present, that is, transmitters located in different locations use the same frequency to broadcast information of the same content at the same time. [0003] At present, in systems such as DVB (Digital Video Broadcast) and DVBT (Digital Video Broadcast-Terrestrial), there is no transmitter identification. When a transmitter fails, it is impossible to accurately and conveniently locate the faulty transmitter machine. Contents of the invention [0004] Aiming at the above...
