We propose a feedback quantization scheme for downlink multiuser diversity systems. The scheme is designed for heterogeneous users, i.e., users operating under different levels of mean signal-to-noise ratios (SNRs). The proposed scheme equally distributes the channel access time to user clusters and, at the same time, maximizes the sum-rate capacity under equal-channel-access-time constraint. The method is compared to a normalized SNR scheduler, full-feedback scheduler, and finite-rate feedback scheduler without fairness consideration to illustrate the performance gaps between different modes of operation.

An Attitude Filtering and Magnetometer Calibration Approach for Nanosatellites Söken, Halil Ersin (Springer Science and Business Media LLC, 2018-03-01) We propose an attitude filtering and magnetometer calibration approach for nanosatellites. Measurements from magnetometers, Sun sensor and gyros are used in the filtering algorithm to estimate the attitude of the satellite together with the bias terms for the gyros and magnetometers. In the traditional approach for the attitude filtering, the attitude sensor measurements are used in the filter with a nonlinear vector measurement model. In the proposed algorithm, the TRIAD algorithm is used in conjunction wi...
Robust Tracking in Cellular Networks Using HMM Filters and Cell-ID Measurements Bshara, Mussa; Orguner, Umut; Gustafsson, Fredrik; Van Biesen, Leo (Institute of Electrical and Electronics Engineers (IEEE), 2011-03-01) A localization algorithm based on cell identification (Cell-ID) information is proposed. Instead of building the localization decisions only on the serving base station, all the detected Cell-IDs (serving or nonserving) by the mobile station are utilized. The statistical modeling of user motion and the measurements are done via a hidden Markov model (HMM), and the localization decisions are made with maximum a posteriori estimation criterion using the posterior probabilities from an HMM filter. The results ...
Transmit Precoding for Flat-Fading MIMO Multiuser Systems With Maximum Ratio Combining Receivers Coskun, Adem; Candan, Çağatay (Institute of Electrical and Electronics Engineers (IEEE), 2011-02-01) We examine the application of transmit precoding in multiuser multi-input-multi-output (MIMO) communication systems with maximum ratio combining (MRC) receivers. In many multiuser applications, the maximum-likelihood or minimum mean-square error (MMSE) receivers can be prohibitive to implement due to their high implementation complexity. We examine the performance of the system with simple MRC receivers and carefully selected precoders, which are designed to compensate the lack of high-complexity receivers,...
Performance analysis of adaptive loading OFDM under Rayleigh fading Canpolat, B; Tanik, Y (Institute of Electrical and Electronics Engineers (IEEE), 2004-07-01) In this paper, we investigate the performance of adaptive loading orthogonal frequency-division multiplexing (OFDM) under Rayleigh fading with maximal ratio-combining (MRC) diversity at the receiver. We assume that channel-state information is available at both the transmitter and the receiver. Closed-form expressions for the lower bound on the average capacity of OFDM transmission under Rayleigh fading are provided for ideal MRC diversity. Simple approximate expressions for the average capacity of the Rayl...
A new likelihood approach to autonomous multiple model estimation Söken, Halil Ersin (Elsevier BV, 2020-04-01) This paper presents an autonomous multiple model (AMM) estimation algorithm for hybrid systems with sudden changes in their parameters. Estimates of Kalman filters (KFs) that are tuned and employed for different system modes are merged based on a newly defined likelihood function without any necessity for filter interaction. The proposed likelihood function is composed of two measures, the filter agility measure and the steady-state error measure. These measures are derived based on filter adaptation rules....
