We propose a per-tone frequency-domain equalization approach for OFDM over doubly-
selective channels. We consider the most general case, where the doubly-selective channel …

This paper observes the inter-carrier interference (ICI) by Doppler effect in time domain in
orthogonal frequency division multiplexing systems. This observation allows us to propose a …

In Orthogonal Frequency Division Multiplexing (OFDM) mobile communication systems time-
varying channels cause an inter-carrier interference (ICI) and degrade the performance due …

In this paper, we consider orthogonal frequency division multiplexing (OFDM) systems with
severe Doppler effect. In the frequency domain, this effect destroys the orthogonality …

In this paper, the problem of time domain equalization in OFDM systems with insufficient
cyclic prefix is discussed. A new algorithm is proposed to produce maximum throughput …
