ABSTRACT = {In this paper, we address the frequency estimator for 2-dimensional (2-D) 
complex sinusoids in the presence of white Gaussian noise. With the use of the sinc 
function model of the discrete Fourier transform (DFT) coefficients on the input data, a 
fast and accurate frequency estimator is devised, where only the DFT coefficient with the 
highest magnitude and its four neighbors are required. Variance analysis is also included 
to investigate the accuracy of the proposed algorithm. Simulation results are conducted to 
demonstrate the superiority of the developed scheme, in terms of the estimation 
performance and computational complexity.},
