A new tracking approach for multipath mitigation based on antenna array [PDF]
, 2011 In Global Navigation Satellites Systems (GNSS), multipaths (MP) are still one of the major error sources. The additional signal replica due to reflection will introduce a bias in conventional Delay Lock Loops (DLL) which will finally cause a strong ...

Multipath traffic splitting algorithm based on adaptive granularity
Tongxin xuebao, 2015 Aiming at the dilemma between load balancing and packet reordering in multipath routing,an adaptive dynamic multipath traffic splitting(ADTS) algorithm was proposed.The algorithm classified Internet flows into two categories:the aggressive and the normal

Efficient Soft-Output GNSS Signal Parameter Estimation using Signal Compression Techniques [PDF]
, 2006 The direct implementation of the maximum likelihood estimator for the time-delay estimation problem is practically intractable for navigation signals due to its complexity, especially when due to multipath reception several superimposed replica are taken
