AI Technical Summary

Technical Problem

Existing BER test methods are inadequate for asymmetric transmission scenarios, particularly in cases where uplink and downlink rates differ significantly, such as in in-vehicle high-definition cameras, leading to inefficiencies in testing and accuracy.

Method used

A communication method utilizing FEC code blocks in sequences to perform BER testing, where the length and composition of sequences are adjusted to match preset BER requirements, allowing for flexible and efficient testing in both asymmetric and symmetric scenarios without additional circuitry.

Benefits of technology

The method simplifies the test process, reduces test time, and improves accuracy by using FEC code blocks as the minimum iterative unit, enabling quick and reliable BER determination in asymmetric transmission scenarios.

Abstract

This invention provides a communication method, apparatus, and system that simplifies the complexity of BER testing of transmission chips. [Solution] The method includes the step of a second device transmitting a first sequence containing P subsequences A to the first device. The first sequence is used by the first device to count a first bit error rate BER, and subsequences A consist of one or more forward error correction FEC code blocks. The method also includes the step of transmitting a second sequence containing Q subsequences B to the first device. The second sequence is used by the first device to count a second BER, and subsequences B consist of one or more FEC code blocks, the length of the second sequence is greater than or equal to the length of the first sequence, and P and Q are positive integers.
