[0070] figure 2 is a flowchart of the decoding method according to the first embodiment of the present invention.
[0071] Such as figure 2 As shown, the decoding method 100 according to the first embodiment of the present invention is applied to a decoder device in mobile communication, and the decoder device includes a first decoding module and a second decoding module. The decoding method 100 includes:
[0072] Step S101: Receive an input coded data service flow through a data channel.
[0073] In this step, an input coded data service stream is received through a data channel (such as an antenna in a mobile terminal). For example, a service refers to a file transmission service, a video service, or a voice service. The encoded data service stream refers to a data stream obtained after encoding service data sent from a base station or other mobile equipment. As is well known to those skilled in the art, in the field of mobile communications, in order to ensure correc...

[0118] Below, refer to Figure 5 An electronic device according to a second embodiment of the present invention is described.
[0119] Figure 5 is a block diagram showing an electronic device 400 according to a second embodiment of the present invention.
[0120] The electronic device 400 includes:
[0121] a communication unit 401 for performing wireless communication; and a decoder device 402 .
[0122] The decoder means 402 include:
[0123] an input terminal configured to receive an encoded data traffic stream input through a data channel;
[0124] a control module configured to determine the type of incoming encoded data stream;
[0125] The first decoding module is configured to input the first type of encoded data service flow into the first decoding module when the type of the encoded data service flow is the first type, and use the first decoding module to encode the first type data traffic streams for decoding; and
[0126] The second decoding module is confi...

Abstract
The invention provides a decoding method, a decoder and electric equipment. The decoding method comprises the steps as follows: receiving a coded data service stream input via a data channel; determining the type of the input coded data service stream; when the type of the coded data service stream is a first class, inputting the first class of coded data service stream into a first decoding module, and using the first decoding module to decode the first class of coded data service stream; and when the type of the coded data service stream is a second class, inputting the second class of coded data service stream into a second decoding module, and using the second decoding module to decode the second class of coded data service stream.
Description
technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, the present invention relates to a decoding method, a decoder device and electronic equipment. Background technique [0002] In recent years, mobile communication standards have gradually developed from 2G to 3G and 4G. In various mobile communication standards, turbo code decoders have gradually become commonly used decoders. Turbo code is a channel coding method with excellent performance close to the Shannon limit, and has been widely used in various mobile communication standards, such as Wimax, LTE, TD-SCDMA, WCDMA, etc. However, due to the high complexity of its decoding method, it has the characteristics of large decoding delay and high power consumption. For mobile terminals, power consumption is a very important key indicator. Therefore, the high-speed Turbo code decoder with low power consumption has always been a difficult point of research. Conten...
