Abstract
The invention discloses an error code measuring method based on pseudo-random code sequence synchronization for a communication system, which comprises the following steps: taking a section of data received by a receiving end as a seed and loading into an LFSR (Linear Feedback Shift Register), thereby generating a pseudo-random code reference digital sequence corresponding to the section of data; comparing the section of data with each bit in the corresponding pseudo-random code reference digital sequence one by one, thereby obtaining the number of the error codes and an error rate; and obtaining a synchronizing result according to a comparison result of the error rate and a preset signal receiving threshold. According to the error code measuring method provided by the invention, an ergodic searching system with low efficiency is not adopted, so that the step of detecting the error codes is simple, the speed is high, the time consumption for calculating a high-order pseudo-random code sequence is greatly reduced and a test result is accurate.
Description
Technical field
The present invention relates to communication system, be specifically related to be used for communication system based on the synchronous measurement of error code method of pseudo-random code sequence.
Background technology
Pseudo noise code binary sequence (Pseudo random binary sequence; PRBS) owing to all be prone to through linear feedback shift register (linear feedback shift register at transmitting terminal and receiving terminal; Be called for short LFSR) produce suitable sequence, therefore in the communication system error rate test, be widely used.Will carry out error code at receiving terminal and calculate, the sequence code stream of receiving terminal needs and the code stream of transmitting terminal carries out bit synchronous, and receiving terminal Serial No. and transmitting terminal code stream Serial No. compare after accomplishing synchronously, carry out Error detection and counting.
The synchronous measurement of error code method of traditional communication system based on pseudo-random code sequence is following: at first produce 2 at receiving terminal
N-1Individual (n is the number of LFSR) sequence of digital bit A; The transmitting terminal data B's that receives of intercepting is a bit of as seed then; In A traversal search and with seed relatively; If the error rate of certain segment data among seed and the A is less than certain signal receive threshold, then expression does not synchronously successfully compare the sequence of equal length among B and the A with error code then and counts.If in A, can not find the situation of the error rate less than certain signal receive threshold, following a bit of among the intercepting B then as seed, traversal search seed in A equally, and the like, until finding the error rate, promptly till the success synchronously less than certain signal receive threshold.
Above-mentioned this method, when the higher or error rate was big when the exponent number of pseudo-random code sequence, the mistake in judgment of several bits can cause amount of calculation to increase in the seed, and therefore, efficient is low, consuming time many.
Summary of the invention
Technical problem to be solved by this invention is to solve based on the synchronous measurement of error code method of the communication system of pseudo-random code sequence, low, the consuming time many problems of efficient.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted provide a kind of be used for communication system based on the synchronous measurement of error code method of pseudo-random code sequence, may further comprise the steps:
The one piece of data that receiving terminal is received is loaded among the linear feedback shift register LFSR as seed, generates and the corresponding pseudo noise code reference number of this segment data sequence;
Each bit in this segment data and the corresponding pseudo noise code reference number sequence is compared one by one, obtained the error code number and the error rate, according to the comparative result acquisition synchronized result of the signal receive threshold of the said error rate and setting.
In said method, obtain synchronized result according to the comparative result of the signal receive threshold of the said error rate and setting and may further comprise the steps:
The more said error rate and said signal receive threshold;
If the current error rate is less than said signal receive threshold, then said synchronized result is success synchronously; Otherwise said synchronized result is synchronously preliminary unsuccessful, continues following one piece of data and is loaded into as seed and recomputates second error rate among the LFSR, more said once more second error rate and said signal receive threshold;
If said second error rate is less than said signal receive threshold, then said synchronized result is success synchronously; Otherwise said synchronized result is unsuccessful synchronously, finishes error code and calculates.
In said method, said signal receive threshold is 0.4.
The present invention utilizes the one piece of data that receiving terminal is received to be loaded among the LFSR as seed, generates and the corresponding pseudo noise code reference number of this segment data sequence; Again each bit in this segment data and the corresponding pseudo noise code reference number sequence is compared one by one; Obtain the error code number and the error rate, thereby obtain synchronized result, because do not adopt the traversal search mechanism of inefficiency; So the Error detection step is simple; Speed is fast, and the calculating of high-order pseudo-random code sequence is consuming time to be reduced greatly, and test result is accurate.
