New bit error rate calculation method

Abstract

The invention discloses a new bit error rate calculation method, which can facilitate derivation and calculation of a bit error rate, reduces the derivation and calculation difficulty of the bit error rate, is very short in test period and easy to popularize, and solves the problems that a large amount of code element data needs to be transmitted and the test period is very long when the bit error rate is accurately measured in the prior art. Therefore, the derivation speed of a user is increased, and the derivation difficulty of an operator is reduced.

Description

technical field [0001] The invention relates to the technical field of bit error rate calculation, in particular to a new bit error rate calculation method. Background technique [0002] The bit error rate is an important indicator to measure the reliability of the communication system. The initial meaning of the bit error rate refers to the ratio of the number of error code elements to the total number of received codes during information transmission. In engineering implementation, in order to reduce bit errors rate, the error detection feedback retransmission method is adopted. In the process of information transmission, there must be interference on the channel and bit errors occur, but the receiving end can detect the bit errors and make the sending end retransmit until it is received correctly. This is essentially In exchange for the loss of transmission efficiency in exchange for reliability, the initial meaning of bit error rate has changed and evolved into the conce...

[0002]The bit error rate is an important index to measure the reliability of the communication system. The initial meaning of the bit error rate means: when information is transmitted, the number of error code elements accounts for The ratio of the total number of codes. In engineering implementation, in order to reduce the bit error rate, an error detection feedback retransmission method is adopted. In the process of information transmission, there must be interference on the channel and bit errors occur, but the receiving end can detect bit errors Come out, let the sender retransmit until it is received correctly, which is essentially a loss of transmission efficiency in exchange for reliability. The initial meaning of the bit error rate has changed, and it has evolved into the concept of the receiving bit error rate, that is, the receiving end The ratio of the number of code elements that are considered correct but actually wrong to the total number of received codes, so that the size of the bit error rate actually depends on the level of verification, and different verification methods have different error detection levels , to accurately measure the bit error rate needs to transmit a large amount of symbol data, the test period is very long, it must be measured by other methods;
