In this paper, the waiting time analysis for an OFDMA wireless cellular system with finite
buffering and Adaptive Modulation and Coding (AMC) is addressed. When AMC is …

To dimension cellular wireless networks, accurate estimates of the cell throughput have to
be available. Consideration of all requirements of future packet-switched networks …

The authors present a performance analysis of orthogonal frequency division multiple
access (OFDMA) based cellular systems with dynamic packet assignment (DPA). Most …

We consider the downlink of an orthogonal frequency division multiplexing (OFDM) based
cell that accommodates calls from different service-classes with different resource …

In this paper we study the downlink of an Orthogonal Frequency Division Multiplexing
(OFDM) based cell that accommodates calls from different service-classes with different …

The objective of the present paper is to build a model which permits to capture and analyze
the principal impacts of fading and multiuser diversity gain on the dynamic performance of …

Multi-carrier Orthogonal Frequency Division Multiple Access (OFDMA) systems promise
enhanced performance as compared to preceding single carrier ones. It is imperative to …

Random access channels (RACHs) in cellular networks are normally designed for Poisson-
distributed arrivals with a constant rate. Unexpected bursty arrivals may result in severely …

In this paper we propose the following approach to the dimensioning of the radio part of the
downlink in OFDMA networks. First, we use information theory to characterize the bit-rate in …

Our objective is to analyze the impact of fading and opportunistic scheduling on the quality
of service perceived by the users in an orthogonal frequency-division multiple access …
