In this paper, we evaluate the Cramer-Rao bounds (CRB) for the estimation of the carrier frequency offset (CFO) for general QAM modulations with no knowledge of the transmitted sequence (blind operation) in frequency hopping (FH) based short burst mode mobile radios. We investigate the blind CFO estimation problem in FH based mobile system that uses multiple short narrowband bursts in different frequency channels for the transmission of one packet. Joint blind channel and CFO estimation over multiple frequency bursts is considered. In the first part of the paper, we determine the limiting performance by finding the CRB for blind estimation, and compare it to the CRB for known data (genie aided) case. The CRB relates the reliability of CFO estimation to the number of radio frequency bursts (RFB) used, constellation and SNR level, and is an important measure for system design without the need to simulate specific algorithms. It is shown that the linear combination (in MMSE sense) of multiple frequency estimates, each obtained from a single RFB independently, achieves the joint CRB over multiple bursts. In the second part of the paper, some practical blind estimation methods are proposed. They are shown to exhibit close performance to the true CRB.

Cut-off Rate based Outage Probability Analysis of Frequency Hopping Mobile Radio under Jamming Conditions Güvensen, Gökhan Muzaffer; Tanık, Yalçın; Yılmaz, Ali Özgür (2010-11-03) This paper deals with the achievable spectral efficiency and outage analysis of short burst frequency hopping (FH) mobile radios under heavy jamming scenarios. With the use of outage probability analysis based on cut-off rate, the maximum spectral efficiency (bits / dimension) and the required number of radio frequency bursts (RFB) (or degrees of freedom) is determined in order to transmit a message reliably for a given target outage probability, number of information bits (message information length) and c...
Analysis of a calibration method for airborne receive-only phased array antennas with self-alignment Elik, Furkan Bahadır; Demir, Şimşek; Department of Electrical and Electronics Engineering (2022-9-15) The calibration of the phased array antennas plays crucial role to ensure the performance of the beam steering capability. Most of the guided missiles utilize phased arrays, thus, the calibration routines should be optimized. Since guided missiles are spatially limited, calibration hardware should not introduce new geometry to the antenna. This limits possible calibration methods of the antennas on the missiles. This study develops a calibration method for semi-active guided missiles and analyzes this metho...
On the Implementation of Optimal Receivers for LFM Signals using Fractional Fourier Transform Candan, Çağatay (2008-05-30) We present a novel receiver structure for the detection and parameter estimation of linear frequency modulated signals. The proposed structure is based on the relations between the fractional Fourier transform and the ambiguity function. It has been shown that the optimal ML receiver, which is the peak detector in the ambiguity plane, can be implemented at a reduced search complexity with the proposed method. The proposed method uses two 1-dimensional search operations in two different fractional Fourier do...
Effect of water-filling method on the PAPR for OFDM and MIMO systems Vural, Mehmet; Akta, Tugcan; Yılmaz, Ali Özgür (2007-06-13) In this paper, the peak-to-average power ratio (PAPR) problem for orthogonal frequency division multiplexing (OFDM) is investigated. The variations in the nature of the problem along with the utilization of water-filling technique are observed and the corresponding cumulative distribution function for PAPR is determined. In addition to OFDM analysis, another analysis is carried out for the comparison of water-filling technique and an equal power distribution algorithm in case of a multiple input multiple ou...
On channel capacity of FSO communication systems in anisotropic non-Kolmogorov strong turbulent atmosphere Ata, Yalcin (The Optical Society, 2019-09-01) Average channel capacity of free space optical (FSO) communication systems using a Gaussian beam with the intensity modulation and direct detection technique is investigated in anisotropic non-Kolmogorov strong turbulent atmosphere. The channel model is selected as gamma-gamma distribution, which is valid for strong turbulence. Obtained results show that anisotropy in both the horizontal and vertical affects the average channel capacity of an FSO communication system positively. Average channel capacity inc...
