Problems solved by technology

[0005] In this regard, due to the decoding method of the frame header signal in the second generation digital satellite broadcasting system, it will still be affected by the phase deviation brought by the transmission channel
Therefore, in order to effectively solve the problem of being more sensitive to its phase deviation in the prior art, and enable the receiving device in the second-generation digital satellite broadcasting system to quickly and accurately decode the physical layer signaling code in the current frame header signal This 7-bit information requires a new decoding method and device for the physical layer signaling code of the second-generation digital satellite broadcasting system

Embodiment Construction

[0020] Hereinafter, the present invention will be described in detail by illustrating various embodiments of the invention by way of drawings. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Additionally, the same reference numbers may be used to denote similar components in the drawings.

[0021] The decoding method and device provided by the embodiments of the present invention can be applied to any receiving device of the second-generation digital satellite broadcasting system. In other words, the present invention does not limit the specific implementation of the second-generation digital satellite broadcasting system. In addition, under normal circumstances, the encoded physical layer signaling code needs to be processed by scrambling and modulation before it can be transmitted through the transmitting device of the second-generation digital satellite broadcasting ...

Abstract

The invention relates to a decoding method and an apparatus, which particularly relates to a decoding method and an apparatus capable of relying on phase deviation effects on a SOF (Start of Frame) sequence in a frame header signal in second-generation digital satellite broadcasting (DVB-S2) to further decode information of seven bits in a physical layer signaling code in the second-generation digital satellite broadcasting system.

Description

technical field [0001] The present invention relates to a decoding method and device, and in particular to a decoding method that can be decoded according to the Start of Frame (SOF) sequence in the frame header signal in the second-generation digital satellite broadcasting (DVB-S2) system. A decoding method and device for compensating for the influence of the phase deviation, so as to further decode the 7-bit information of the physical layer signaling code (Physical Layer Signaling Code) in the second generation digital satellite broadcasting system. Background technique [0002] DVB-S2 is the second-generation digital satellite broadcasting standard developed on the basis of the previous generation DVB-S. Therefore, compared with the DVB-S system, the second-generation digital satellite broadcasting system has better performance improvement in terms of transmission capacity, modulation and error correction. For example, in terms of forward error correction (Forward error...
