A New IFO Estimation Scheme for Orthogonal Frequency Division Multiplexing Systems
نویسندگان
چکیده
We address a new integer frequency offset (IFO) estimation scheme with an aid of a pilot for orthogonal frequency division multiplexing systems. After correlating each continual pilot with a predetermined scattered pilot, the correlation value is again correlated to alleviate the influence of the timing offset. From numerical results, it is demonstrated that the influence of the timing offset on the IFO estimation is significantly decreased. Keywords—Estimation, integer frequency offset, OFDM, timing offset.

Integer Frequency Offset Synchronization Scheme with Low Implementation Complexity for OFDM Systems
In this paper, a low-complexity integer frequency offset (IFO) estimation scheme is proposed for an orthogonal frequency division multiplexing (OFDM) based digital radio mondiale plus (DRM+) system. In order to reduce the complexity of the IFO estimation, this paper addresses a grouping of time reference cell (TRC) pilot subcarriers in DRM+ system. The grouping method of TRCs is using the chara...

We address the integer frequency offset (IFO) estimation under the influence of the timing offset (TO) in orthogonal frequency division multiplexing (OFDM) systems. Incorporating the IFO and TO into the symbol set used to represent the received OFDM symbol, we investigate the influence of the TO on the IFO, and then, propose a combining method between two consecutive OFDM correlations, reducing...

This paper deals with the integer frequency offset (IFO) estimation for orthogonal frequency division multiplexing (OFDM)-based digital video broadcasting-terrestrial (DVB-T) systems. In the conventional scheme, the decision variable is based on the limited number of the correlations and ratios of pilots of the received samples, and thus, the decision variable contains only a small portion of t...
