In this paper, a novel adaptive resource allocation in downlink orthogonal frequency division
multiplexing wireless system is investigated. Different from the conventional algorithms, user …

The aim of the paper is to study the problems of resource management in the presence of
inter-carrier interference (ICI) and multipath fading channel for orthogonal frequency division …

It is well known that orthogonal frequency division multiplexing (OFDM) is robust to
frequency-selective fading in wireless channels. However, it is sensitive to carrier frequency …

In this paper, we study the adaptive resource allocation in multiuser orthogonal frequency
division multiplexing (OFDM) systems. We try to maximize the sum capacity of an OFDM …

The key issues in the design of a multiuser orthogonal frequency division multiplexing (MU-
OFDM)-based systems are the subcarrier, power, and the bit allocation. Conventionally, the …

It is generally hard to find the optimal solution for sub-channel and power allocation for a
multiuser Orthogonal Frequency Division Multiplexing (OFDM) system that maximizes the …

Previously, a scheme in [1] is proposed for the subcarrier, bit, and power allocation problem
to minimize the total transmit power for multiuser orthogonal frequency division multiplexing …

The Orthogonal Frequency Division Multiplexing (OFDM) transmission is the optimum
version of the multicarrier transmission scheme, which has the capability to achieve high …
