Embodiment Construction

[0038] figure 2 An embodiment of a CIF framing method is shown.

[0039] In step 21, the location information of each sub-channel in the CIF is obtained.

[0040] It should be noted that a CIF is composed of 864 capacity units (Capacity Unit, CU), a CIF includes at least one sub-channel, and each sub-channel is composed of at least one CU. A subchannel can be composed of continuous CUs or discrete CUs. For the convenience of system implementation, a better way is that sub-channels are composed of consecutive CUs.

[0041] In the case that each sub-channel is composed of consecutive CUs, the location information of the sub-channel mainly includes the starting location information of the sub-channel CU and the number information of the CU. Since each sub-channel is composed of consecutive CUs, the position of the sub-channel can be known after obtaining the starting position and the number of CUs of a certain sub-channel.

[0042] In step 22, the symbol mapping mode of each...

Abstract

Disclosed is a public interleaving frame framing method which includes obtaining the symbol mapping method and position information of each sub-channel in the public interleaving frame, determining the bit number contained in a CU (containing unit) in each sub-channel according to the symbol mapping method of each sub-channel, and correspondingly arranging the data bit in each sub-channel according to the position information of each sub-channel and the bit number contained in the CU. The method can help technique personnel in related field to realize forming the data bit to CIF at the transmitting end of a T-MMB system. The public interleaving frame framing method of the invention also provides a public interleaving frame framing device.

Description

[0001] This application claims the priority of the patent application with the application number 200810112080.4, the application date is May 21, 2008, and the invention name is "framing method and framing device for public interlaced frames". The entire content of this patent application has been reflected in this application. technical field [0002] The present invention relates to a framing technology in a mobile communication system, in particular to a framing method for public interleaving frames and a framing device for public interleaving frames. Background technique [0003] Currently, the world's mainstream mobile TV / mobile multimedia broadcast transmission standards include Digital Audio Broadcast (DAB) series standards, Digital Video Broadcasting Handheld (DVB-H) for handheld devices, and MediaFLO technology. In terms of channel bandwidth, the DAB series standard uses the working mode of 1.712MHz bandwidth, and DVB-H and MediaFLO use the working mode of 8MHz band...
