In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic pre痻, a guard space between OFDM symbols, provide su眂ient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻 allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.

当前工程上广泛采用了一种高效滤波器，即CIC（cascaded integrator-comb filter）将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)
