In recent years, the demand for wireless connectivity has skyrocketed, leading to explosive growth in industrial wireless communications. The increasing need for fast and reliable wireless connections necessitates efficient utilization of the limited radio frequency (RF) spectrum resources. Due to the accelerating demand of the commercial wireless communications industry and other RF applications, the RF spectrum is becoming increasingly crowded. Over the last decade, new concepts with the potential to contribute towards significant improvements in the efficiency of radio spectrum utilization and protection of passive sensing services have been introduced. This led to the development of several co-existence solutions based on simultaneous operations of wireless services and other RF applications within the same frequency band.
Recently, the emerging concept of RF spectrum cohabitation based on allowing communication systems and other RF applications to share their resources has attracted significant interest from researchers and practitioners. For example, competition over bandwidth between radar and communications can be directly alleviated if the two systems are allowed to share their resources and/or be deployed on a single platform. This can be achieved via jointly designing the radar and communication systems. The waveforms can be hosted on the same platform and used independently or utilized jointly and hosted in the same platform. Co-design and simultaneous operation can also be achieved for communications systems as well as other wireless applications such as radio telescope, radio telemetry, wireless power transfer, internet of things, and military radios.
The main thrust of this special issue is the co-existence between wireless communications and other users of the RF spectrum. Cognitive radio, in which multiple wireless communications users are able to share the same bandwidth, is outside the scope of this issue.
