Problems solved by technology

However, in reality, due to the existence of various factors such as interference and noise, the Manchester encoded signal received by the receiving end will contain glitch levels, and high-level compression (low-level stretching) or low-level compression (low-level compression) will also appear. High level stretching) phenomenon may lead to decoding errors

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] see Figure 5 , in one embodiment, a kind of Manchester coded signal decoding method, comprises:

[0030] Step 501, receive a Manchester coded signal.

[0031] Step 502: Determine the sampling period according to the theoretical header level duration of the Manchester coded signal, uniformly set the same number of N sampling points in the two sampling periods before and after each symbol, and obtain each sampling Points correspond to high and low levels.

[0032] Specifically, an odd number of N sampling points is uniformly set in the two sampling periods before and after each symbol, and...

Abstract

The present invention discloses a Manchester encoding signal decoding method. The method comprises the steps of receiving a Manchester encoding signal; according to the theoretical head level duration of the Manchester encoding signal, determining the sampling cycles, and setting a plurality of sampling points of same numbers in the front and back two sampling cycles of each code element evenly, and obtaining the corresponding high and low levels of each sampling point; according to the number of the high level sampling points in the front and back two sampling cycles of the code element, correcting the Manchester encoding signal; according to a Manchester encoding rule, decoding a corrected data signal. The present invention also discloses a Manchester encoding signal decoding device correspondingly. By applying the technical scheme of the present invention, the decoding accuracy can be improved.

Description

technical field [0001] The present invention relates to the technical field of data decoding, in particular to a method and device for decoding Manchester coded signals. Background technique [0002] Manchester encoding (Manchester Encoding) is a synchronous clock encoding technology, which is widely used in network data transmission. In this patent document, "Manchester encoded signal" is used to specifically refer to data that is encoded using Manchester encoding rules and then transmitted. [0003] In the Manchester coding rules, there is a jump in the middle of each bit of data in the Manchester coded signal. A transition from a high level to a low level represents a data bit "1", and a transition from a low level to a high level represents a data bit. "0", this transition is used as data and also provides a clock signal. In traditional technology, a data sequence "001101" in a Manchester encoded signal such as figure 1 shown. [0004] It can be seen that each bit of...
