Abstract EN
Cognitive radio (CR) is a promising concept for improving the utilization of scarce radio spectrum resources.
Orthogonal frequency division multiplexing (OFDM) is regarded as a technology which is well matched for CR systems.
It is shown that channel estimation errors can result in a severe performance degradation in a multiuser OFDM CR system.
A simple back-off scheme is proposed, and simulation results are provided which show that the proposed scheme is very effective in mitigating the negative impact of channel estimation errors.
