OFDM is becoming widely applied in wireless communications systems due to its high rate
transmission capability with high bandwidth efficiency and its robustness with regard to multi …

Within the wide range of issues related to 4G wireless networks, due to the scope of the
ISSTA conference, in this presentation we highlight some segments of wireless networks …

This paper deals with two major considerations for pilot symbol assisted orthogonal
frequency division multiplexing (PSA-OFDM) systems when operated over Rayleigh fading …

By bilinearly transforming the rectangularly pulsed multicarrier basis signals, new basis sets
containing full-response continuous basis signals are developed for constructing spectrally …

Transmit diversity can be applied to OFDM systems by adopting space time code. Since the
received signal is the overlapped signals transmitted from different transmit antennas …

This paper presents a semi-analytical methodology for radio link level performance analysis
in a multirate" orthogonal frequency-division multiple-access"(OFDMA) network with …

For the practical LMMSE channel estimation of MIMO-OFDM systems, the high
computational complexity of LMMSE needs to be eliminated. In this study, we develop a low …

This paper proposes a computationally efficient nondata-aided maximum a posteriori (MAP)
channel-estimation algorithm focusing on the space-frequency (SF) transmit diversity …

In this paper, we propose a novel scheduling scheme for the downlink of IEEE 802.16
networks. A scheduler at the Base Station (BS) decides the order of downlink bursts to be …

The authors present an analysis of the effect of timing offset on channel estimation for comb-
type pilot-aided orthogonal frequency division multiplexing (OFDM) systems. Residual …
