In the literature, Liu and Tureli proposed a blind method to solve such a problem , making use of the fact that not all subcarriers are used for data transmission. However, the computational complexity of this method is very high. In , the author introduced a low complexity carrier offset estimation method based on lower-order Taylor series approximation on the cost function. In this paper, from the method in , we develop an iterative carrier offset estimation method which leads to significant performance gain in both MSE of carrier offset estimation and the symbol error rate (SER). © 2005 IEEE.||Source Title:||Proceedings - 8th International Symposium on Signal Processing and its Applications, ISSPA 2005||URI:||http://scholarbank.nus.edu.sg/handle/10635/69518||ISBN:||0780392434||DOI:||10.1109/ISSPA.2005.1580211|
