Wireless communication systems and networks are becoming extremely popular because of cost effectiveness,
mobility and flexibility and as such the demand for high-speed wireless communication services is growing rather
rapidly. However, wireless systems do face a number of challenges including spectral efficiency, performance
reliability, power requirement, QoS, security, and complexity and flexibility of the architecture. Both academia and
industries are focusing on research in wireless systems and networks significantly, which motivated the publication of the current Special Issue in wireless communications.
