Embodiment Construction

[0060] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0061] As shown in Figure 1, the method for MediaFLO terminal demodulation according to the present invention comprises:

[0062] S102, receiving a plurality of original data from the channel;

[0063] S104, performing correlation value calculations on multiple raw data and 16 sets of pre-stored data to calculate 16 correlation values; and

[0064] S106. Acquire a demodulation value corresponding to the channel according to the 16 correlation values.

[0065] As shown in Figure 2, the demodulation device 10 for MediaFLO terminal according to the present invention includes:

[0066] a receiving unit 20, configured to receive multiple raw data from the channel;

[0067] The calculation unit 30 is used to perform correlation value calculations on multiple raw data and 16 sets of pre-stored data to calculate 16 correlation values; and

[0068] The comparison uni...

Abstract

The disclosed method for MediaFLO terminal demodulation comprises: 1. receiving multiple original data from channel; 2. calculation the correlation value with the received data and stored 16-group data to obtain 16 correlative values; and 3. accordingly obtaining the demodulation value, wherein if the maximal correlative value less than a threshold, it takes the coarse synchronization operation again; or else, it takes the maximal correlative value as the relative demodulation value.

Description

technical field [0001] The present invention relates to a demodulation method and device for a mobile terminal, in particular to a demodulation method and device for a MediaFLO system terminal. Background technique [0002] In the field of mobile TV communication, the MediaFLO (Media Forward Link Only, only forward link media technology) system has received more and more attention. The MediaFLO system is a comprehensive multimedia transmission service solution for network operators, and also provides users with more timely, thoughtful and satisfactory experience. [0003] The MediaFLO system consists of two parts: FLO technology and MediaFLO media distribution system. FLO technology is a new air interface (Air Interface) specially designed for wireless users to use mobile multimedia services, which is the abbreviation of "Forward Link Only"; MediaFLO media distribution system provides a low-cost multimedia content distribution mode. [0004] FLO technology is specially opt...
