Blind-phase noise estimation in OFDM systems by sequential Monte Carlo method

Authors:Panayırcı, Erdal; Çırpan, Hakan Ali; Moeneclaey, Marc; Noels, Nele
Publisher and Date:(John Wiley and Sons Ltd, 2006)

One of the main drawbacks of orthogonal frequency division multiplexing (OFDM) systems is the phase noise (PN) caused by the oscillator instabilities. Unfortunately due to the PN the most valuable feature namely orthogonality between the carriers is destroyed resulting in a significant degradation in the performance of OFDM systems. In this paper based on a sequential Monte Carlo method (particle filtering) a computationally efficient algorithm is presented for estimating the residual phase noise ...
Monte Carlo Solutions for Blind Phase Noise Estimation

Authors:Simoens, Frederik; Duyck, Dieter; Cirpan, Hakan Ali; Panayirci, Erdal; Moeneclaey, Marc
Publisher and Date:(Springer International Publishing Ag, 2009)

This paper investigates the use of Monte Carlo sampling methods for phase noise estimation on additive white Gaussian noise (AWGN) channels. The main contributions of the paper are (i) the development of a Monte Carlo framework for phase noise estimation with special attention to sequential importance sampling and Rao-Blackwellization (ii) the interpretation of existing Monte Carlo solutions within this generic framework and (iii) the derivation of a novel phase noise estimator. Contrary to the ...
