Rate adaptive downlink resource allocation in orthogonal frequency division multiple access
system is a constraint optimization problem, which is to maximize the minimum data rate of …

In multiple users MIMO-OFDM system allocates the available resources to the optimal users
is a difficult task. Hence the scheduling and resource allocation become the major problem …

A multicell multiuser massive multiple‐input‐multiple‐output (MIMO) network with Rician flat
fading is considered. Given channel reciprocity, non‐orthogonal uplink channel training in …

Even with the implementation of the 'best'spectrum sensing techniques, the amount of
spectrum resource that could be made available for the cognitive radio networks may still be …

The limited electromagnetic radio spectrum can be managed efficiently to accomplish the
requirements of various users by the use of cognitive radio networks (CRN). Resource …
