Embodiment 1

[0038] This embodiment provides a signal receiving method, which can be applied at a signal receiving end.

[0039] figure 1 It is a flow chart of the signal receiving method provided in this embodiment. As shown in 1, the method mainly includes the following steps (step S102-step S110).

[0040] Step S102, get 2 N The corresponding relationship between each bit string and time interval in a bit string whose length is N, wherein, 2 N The bit strings are different from each other, and the time intervals corresponding to different bit strings are different, N≥1.

[0041] In this embodiment, a bit string with a length of N may correspond to one time interval, or may correspond to multiple time intervals, as long as the time intervals corresponding to different bit strings are different.

[0042] In an optional implementation of this embodiment, 2 may be obtained according to the current data transmission time parameter N The corresponding relationship between each bit string ...

Embodiment 2

[0074] This embodiment provides a signal receiving method, Figure 5 It is a flow chart of the signal receiving method provided by this embodiment. Figure 6 It is a flow chart of an optional signal receiving method provided in this embodiment. Such as Figure 5 and 6 As shown, the difference between the method provided in this embodiment and the method provided in Embodiment 1 is that in Embodiment 1, the receiver judges whether each signal is a valid signal in sequence after receiving Y+1 signals, while this In an embodiment, after the first valid signal is determined, each time a signal is received, it is immediately judged whether the signal is a valid signal. Compared with Example 1, the method provided by this example has higher efficiency.

[0075] Such as Figure 5 As shown, the signal receiving method provided in this embodiment mainly includes the following steps (step S202-step S208).

[0076] Step S202, get 2 N The corresponding relationship between each bit...

Embodiment 3

[0113] This embodiment provides a signal receiving device, which is used to implement the signal receiving method described in Embodiment 1.

[0114]In this embodiment, the signal receiving device may be an electronic payment device having but not limited to functions of a smart card and / or a smart key device and / or an OTP token.

[0115] Figure 7 is a schematic structural diagram of a signal receiving device provided in this embodiment, such as Figure 7 As shown, the device includes: a time interval acquiring unit 120 , a receiving unit 110 , a recording unit 140 , a judging unit 130 and an effective signal acquiring unit 150 . Each will be described below.

[0116] Time interval acquisition unit 120, used to acquire 2 N The corresponding relationship between each bit string and time interval in a bit string whose length is N, wherein, 2 N The bit strings are different from each other, and the time intervals corresponding to different bit strings are different, N≥1.

Abstract

Disclosed are a method and device for receiving signals. The method for receiving signals comprises: acquiring a correlation between every bit string in 2N bit strings with lengths of N and a time interval, wherein the 2N bit strings are different from one another, different bit strings correspond to different time intervals, and N≥1; receiving Y+1 signals, wherein the first signal in the Y+1 signals is a signal used for indicating that data transmission starts, Y≥1, Y is a positive integer, and Y+1 is the total number of the signals received; determining the signal used for indicating that data transmission starts as a first valid signal; determining whether a time interval between a start time point at which the Zth signal is received and a start time point at which a previous valid signal is received is one time interval in the acquired correlations, and if yes, recording the Zth signal as a valid signal, wherein z=2, 3, 4, …, Y+1; and obtaining X valid signals according to the determining results, X≤Y+1, and X being a positive integer.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a signal receiving method and device. Background technique [0002] In the process of data transmission, there is usually noise signal interference in the channel, and its manifestation is the same as that of the data signal, which will cause data decoding failure or the decoded data is wrong. Therefore, eliminating noise as much as possible becomes a key factor to improve the success rate of data communication. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned problems. [0004] The main purpose of the present invention is to provide a signal receiving method. [0005] Another object of the present invention is to provide a signal receiving device. [0006] In order to achieve the above object, the technical solution of the present invention is specifically realized in the following way: [0007] One aspe...
