Novel time delay estimation algorithm for ADS-B based on an auxiliary source and correntropy
A novel time delay estimation algorithm was proposed to correct ADS-B latency employing an auxiliary signal source and correntropy.Firstly,the cause of message delay was analyzed and a new latency model was raised.Secondly,when comparing the signal similarity,the correntropy was introduced to estima...

| description | A novel time delay estimation algorithm was proposed to correct ADS-B latency employing an auxiliary signal source and correntropy.Firstly,the cause of message delay was analyzed and a new latency model was raised.Secondly,when comparing the signal similarity,the correntropy was introduced to estimate the delay using Doppler shift from signals of the auxiliary source as the research object.Thirdly,the influnce of step length and Gaussian kernel length on evaluating the time delay was researched.Finally,simulations were carried out to verify the performance of the proposed algorithm in the impulsive noise environment.The new algorithm needs no change in message format and it is more practical and accurate compared with existing methods. |
