A two-path model, where each path includes a linear Doppler frequency offset, is commonly applied for modeling aeronautical channels under an en-route scenario. In this study, a maximum-likelihood (ML) channel estimation-based channel response differential correlation method is used to estimate a bilinear Doppler frequency offset. Specifically, reference symbols and ML estimation are used to obtain...
In this paper, we propose an iterative SSS detection scheme for neighbor cell search in 3GPP LTE systems. The proposed scheme contains three stages for each iteration. At the first stage, SSS is detected without channel information and a candidate cell is selected. Then a coherent detection is utilized with channel response estimated from the candidate's SSCH at the second stage, in which a corresponding...
