In this paper, we present various visualizations for the Text Re-use found between texts of a
collection to support humanists in answering a broad palette of research questions. When …

This paper addresses the problem of Doppler spread and carrier frequency offset (CFO)
estimation under flat-fading Rayleigh channels. We develop a new low-cost and robust …

Joint scheduling and resource allocation in uplink orthogonal frequency-division
multiplexing (OFDM) systems is complicated and even becomes intractable with a large …

Orthogonal frequency-division multiple access (OFDMA) systems divide the available
bandwidth into orthogonal subchannels and exploit multiuser diversity and frequency …

Hardware constraints, which motivate receive antenna selection, also require that various
antenna elements at the receiver be sounded sequentially to obtain estimates required for …

The maximum likelihood (ML) Doppler spread estimator provides an accurate estimation
performance; however, it results in a much higher computation cost. In this work, we propose …

This paper proposes an efficient, low-complexity, and near-optimal approach to pilot-
assisted fast-fading channel estimation for single-carrier modulation with a turbo equalizer …

In this paper, rate and subcarrier bandwidth adaptation (RSBA) on the average spectral
efficiency of orthogonal frequency-division multiplexing (OFDM) systems using M-ary …

The lack of accurate and efficient channel estimation (CE) for multiple-input-multiple-output
(MIMO) channel state information (CSI) has long been the stumbling block of near-MIMO …

Representing the channel varying rate and the mobile speed of a mobile terminal directly,
Doppler shift is an important parameter in vehicular mobile communications and therefore is …
