Joint carrier frequency offset (CFO) and channel estimation for uplink MIMO-OFDMA
systems over time-varying channels is investigated. To cope with the prohibitive …

We introduce a new sequential importance sampling (SIS) algorithm which propagates in
time a Monte Carlo approximation of the posterior fixed-lag smoothing distribution of the …

A new joint frequency offset and channel estimator for cooperative relay networks operating
over time-varying multipath channels based on Gauss–Hermite integration (GHI) and …

In modern multiuser communication systems, users are allowed to enter or leave the system
at any given time. Thus, the number of active users is an unknown and time-varying …

Particle filters have been widely used in solving nonlinear filtering problems. Proposal
Distribution design is a key issue for these methods and has vital effects on simulation …

蒙特卡洛方法对固定标签**滑分布进行**似, 通过准确估计最佳重要性分布可以将计算量降低,
并可以提高误码率性能. 但是, 该算法中采用卡尔曼滤波实现对线性高斯模型下状态的最优估计 …

An improved fixed-lag particle smoother in the mixture Kalman filter (MKF) framework is
developed for the blind equalization in time-varying multiple-input multiple-output (MIMO) …

In this paper, a new joint carrier frequency offset (CFO) and channel estimator is proposed
for wireless cyclic prefixed single-carrier (CP-SC) systems. A novel Rao-Blackwellized …

Equalization of unknown frequency-and time-selective multiple input multiple output (MIMO)
channels is often carried out by means of decision feedback receivers. These consist of a …

We develop three methods for the joint symbol detection, frequency offset and channel
estimation in time-varying multiple-input multiple-output channels with multiple frequency …
