Embodiment 1

[0045] figure 1 It is a schematic structural diagram of an error detection device provided by an embodiment of the present invention. Such as figure 1 As shown, the error detection device provided in this embodiment includes:

[0046] Transmitter 1 is used to transmit the test pseudo-random sequence code obtained by transforming the pseudo-random sequence code to the test equipment;

[0047] The receiving end 2 is used to receive the test sequence code output by the test equipment for error detection, and the test sequence code is the sequence code outputted by the pseudo-random sequence code transmitted by the equipment under test.

[0048] Specifically, pseudo-random sequence code is a code stream generated by imitating the random characteristics of random sequence, which has good self-correlation and good statistical characteristics. In this embodiment, the transmitting terminal 1 transmits the test pseudo-random sequence code obtained by transforming the pseudo-random sequence c...

Embodiment 2

[0054] This embodiment is a supplementary explanation to the above embodiment. figure 2 It is a schematic structural diagram of an error detection device according to another embodiment of the present invention. image 3 It is a schematic structural diagram of the bit synchronizer 21 in the error detection device according to another embodiment of the present invention. Figure 4 It is a schematic structural diagram of the local code generator 22 in the error detection device according to another embodiment of the present invention. This embodiment mainly supplements the bit synchronizer 21, the local code generator 22, etc. of the above embodiment.

[0055] Specifically, the bit synchronizer 21 includes: a transition edge capture module 211, a status register 212, and a controllable counter 213. For example, the bit synchronizer 21 first extracts the clock signal of the test sequence code and the test pseudo-random sequence code obtained from the transmitter 1 and inputs them to...

Abstract

The invention provides an error code detection device, which belongs to the technical field of communication detection. The error code detection device comprises a transmitting end and a receiving end, wherein the transmitting end is used for transmitting a test pseudorandom sequence code obtained through converting and processing a pseudorandom sequence code to a test device; and the receiving end is used for receiving a test sequence code outputted by the test device for error code detection, and the test sequence code is the sequence code outputted when the pseudorandom sequence code is transmitted through a to-be-detected device. The pseudorandom sequence code has good self correlation and good statistical properties. By using the pseudorandom sequence code as a standard test signal, the error code detection accuracy can be improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication detection, and in particular to an error detection device. Background technique [0002] The error code tester is a tool for evaluating the data transmission quality of communication equipment through the error index of the communication equipment. [0003] The error code tester generally includes a transmitter and a receiver. The transmitter sends a certain code type serial code to the communication device, and the receiver receives the serial code output by the communication device, and then compares and analyzes how many error codes are transmitted through the communication device. [0004] The traditional error code tester has a small choice of code pattern and cannot accurately perform error code testing. Summary of the invention [0005] In view of this, one of the technical problems solved by the embodiments of the present invention is to provide an error detection device, whic...
