This paper, patent pending, put forwards a novel low complexity channel estimator for a
special case of comb-type pilot pattern with pilot interval I= 2, which can combat the effect of …

(OFDM) systems need accurate channel estimation in order to compensate for the
distortions caused by propagation through the dispersive channel. This work compares two …

The channel estimation techniques for OFDM systems based on pilot arrangement are
investigated. The channel estimation based on comb type pilot arrangement is studied …

In this paper, a new channel estimation technique is presented that can improve the
performance of channel estimation with fewer pilot symbols transmitted than would be …

The thesis is largely built on a collection of published and submitted papers where the main
focus is to analyze and optimize single-carrier adaptive coded modulation systems with and …

Orthogonal Frequency Division Multiplexing (OFDM) has been recently applied widely in
wireless communication systems, due to its high data rate, transmission capability with high …

Wireless communication systems incorporating coherent OFDM requires the estimation and
tracking of the time-varying channel response for accurate demodulation of data at the …

Based on frequency domain pilot channel estimation is a typical technology of channel
estimation in OFDM system. In most cases, the pilot configuration of the system can't start …

We provide a comparative study of channel estimation methods for pilot-assisted orthogonal
frequency-division multiplexing (OFDM) communication systems in time-varying frequency …
