Phase Noise in MIMO Systems: Bayesian Cramér–Rao Bounds and Soft-Input Estimation
2013
IEEE Transactions on Signal Processing

., filtering, and offline, i.e., smoothing, estimation of phase noise over the length of a frame are derived. ...
To reduce the overhead and complexity associated with tracking the phase noise processes over the length of a frame, a novel soft-input extended Kalman filter (EKF) and extended Kalman smoother (EKS) that ...
In [15] , pilot-aided estimation of phase noise in single carrier MIMO systems is investigated, where a Wiener filter is applied to eliminate the ambiguity in the estimation problem and to obtain the ...

The starting point for all the algorithms is the implementation of soft-input soft-ouput maximum a posteriori (MAP) symbol detection strategies for transmissions over channels encompassing unknown parameters ...
ABSTRACT | In this paper, we present an overview on the design of algorithms for iterative detection over channels with memory. ...
Hence, the gap between the Bperfect CSI[ curve and the others is uniquely due to the need for phase estimation/compensation, and not to the rate decrease due to pilot symbols. 1) Phase-Uncertain Communications ...

The channel is estimated using a Kalman filter (KF) followed by a zero-phase filter (ZPF) as a smoother. ...
The contributions of this dissertation are as follows: i) An accurate, low-complexity approach to pilot-assisted fast-fading channel estimation for single-carrier modulation with a turbo equalizer and ...
At each iteration, the estimated channel gains from the KF are passed through the ZPF with the forward (and backward) magnitude response A(f ). ...
