“…Many excellent works on the topic of CFO estimation have been reported by other researchers [3][4][5][6][7][8][9][10][11][12][13][14]. Among these contributions, according to whether the CFO estimators use training sequences or not, they could be classified as blind ones [3][4][5] and data-aided ones [6][7][8][9][10][11][12][13][14]. Focusing on blind approaches, Beek develops a maximum likelihood (ML) estimator in [3] by exploiting the redundancy in the cyclic prefix (CP).…”

“…Focusing on blind approaches, Beek develops a maximum likelihood (ML) estimator in [3] by exploiting the redundancy in the cyclic prefix (CP). Liu and Tureli take advantage of the known OFDM subspace structure due to the placement of virtual subcarriers and propose blind estimation methods reminiscent of spectral analysis techniques in array processing, i.e., MUSIC and ESPRIT [4,5]. Opposite to blind approaches, data-aided CFO estimation can be accomplished with the aid of training sequences.…”

“…In wireless communications, the carrier frequency offset (CFO) [1,2] is primarily caused when the frequencies of the oscillators between the transmitting and receiving ends do not match or there is a Doppler frequency shift that is proportional to the carrier frequency, as well as to the moving speed of the mobile unit. For orthogonal frequency division multiplexing (OFDM) systems [3,4], the quality of the signal transmission is liable to degrade in the case of the existence of CFO.…”

“…In the past, a number of works (e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]) have been devoted to the CFO estimation techniques. The least square (LS) criterion is used in [8] for CFO estimation.…”
