Iterative MMSE estimation of SINR for turbo-coded FH-SS systems in partial-band interference and fading channels

The minimum mean square error (MMSE) estimate of the signal-to-interference-and-noise ratio (SINR) is derived for turbo-coded slow frequency hopping systems in the presence of partial-band interference and Rayleigh fading. The MMSE estimator operates without training symbols and iteratively uses the turbo decoder extrinsic information to improve the accuracy of the SINR estimate. Performance comparisons are made with a genie-aided MAP-based estimator and near-optimal performance is obtained for all but impractically small hop sizes. Copyright © 2010 John Wiley & Sons, Ltd.
