Orthogonal Frequency Division Multiplexing (OFDM) is a advance bandwidth efficient digital
modulation technique highly adopted for the broadband wireless services because it gives …

In practical multiple input multiple output (MIMO) systems, accurate knowledge of the
channel state information (CSI) is a prerequisite to guarantee the system performance. The …

In this paper, we investigate new methods for preamble-aided coarse timing estimation in
orthogonal frequency division multiplexing systems. Two novel timing metrics using high …

This paper proposes a new paradigm of shared spectrum access between cellular wireless

We consider receiver synchronization in the non-continguous orthogonal frequency division
multiplexing (NC-OFDM)-based radio system in the presence of in-band interfering signal …

The minimum average signal-to-noise ratio (SNR) per bit required for error-free transmission
over a fading channel is derived, and is shown to be equal to that of the additive white …
