… We propose a message-passing algorithm of joint channel estimation and decoding for
OFDM systems, where expectation propagation is exploited to deal with channel estimation. …

… In this paper, the effect of pilot contamination on downlink channel estimation is ignored,
as frequency-division multiplexing pilot scheme and time-division multiplexing pilot scheme …

… In this paper, we present a blind channel estimation and symbol detection scheme for … on
expectation propagation (EP). The proposed algorithm is initialized with the channel estimation …

… section we discuss the problem of MIMO channel estimation based on a pilot sequence. We
will show that by taking into consideration the channel estimation error, the search area can …

… channel estimation algorithm for the downlink of massive MIMO systems. This algorithm
employs the expectation propagation and expectation … prior distribution on the channels. Its …

… Then, Algorithm 2 applies EP to reestimate the … proposal as Kalman smoothing expectation
propagation (KSEP) turbo … both a priori information and channel estimation errors on the MAP …

… However, when this framework is applied jointly to detection and channel estimation, discrete
and continuous random variables appear in the FG and the SPA becomes impractical. A …

… , the receiver can estimate (normally imperfectly) the channel based on the transmitted pilot
… detection based on the channel estimate. Channel estimation and data detection can also be …

… In this paper, a novel category of expectation propagation (EP) based frequency domain (FD)
semi-blind receivers are proposed for single-carrier block transmissions. A recently …

… Joint decoding and channel estimation would be a natural extension of this work. For dynamic
systems with nonlinear and non-Gaussian likelihoods different from the signal detection …
