The performance of channel estimation in orthogonal frequency division multiplexing
(OFDM) systems significantly depends on the pilot signal, which is usually scattered in time …

In TDS-OFDM (time-domain synchronous orthogonal frequency division multiplexing)
systems, pseudonoise (PN) sequences rather than cyclic prefixes are inserted as guard …

We present queueing analysis for two connection admission control (CAC) schemes for
OFDM wireless networks. The first one is a threshold-based CAC scheme in which …

In this work, we apply RF carrier frequency hopping to orthogonal frequency-division
multiplexing (FH-OFDM). Achievable hop rate and bandwidth efficiency are determined …

This paper investigates the problem of dynamic multiuser resource allocation in the
downlink of OFDMA system. To overcome the users' buffer overflow, a greedy algorithm is …

In this paper, we analyze the radio link level queueing performance of a OFDM/TDMA
network under Rayleigh fast fading channel. The probability mass function of transmission …

In this paper, we propose a utility-approached radio resource allocation (RRA) algorithm for
downlink transmission in orthogonal frequency division multiple access (OFDMA) cellular …

In this paper, a comparative investigation on various channel estimation and equalization
algorithms for OFDM based high rate wireless MAN networks is presented and analyzed in …

Les travaux de recherche présentés dans cette thèse ont pour but l'étude et l'optimisation
d'un système de communications à haut-débit sur lignes électriques, mettant en œuvre les …

We address the problem of universal decoding in unknown frequency-selective fading
channels, using an orthogonal frequency-division multiplexing (OFDM) signaling scheme. A …
