Signal Processing for 5G Wireless

Signal processing will be of paramount importance in future 5G networks to make efficient use of resources, resolve conflicts, reduce signaling load, improve the transfer of information, improve security, make efficient use of energy consumption, reject interference, and enable efficient detection of spectrum opportunities. 

The number of wireless connections is growing exponentially around the globe. It is expected that up to 50 billion devices will be connected to the net by 2050. Most of these connections will involve wireless technologies. However, with current wireless standards, it will be impossible to cope with this increase in traffic demand and different quality of service requirements. In addition, the signaling load needed for resource allocation and device coordination in such massive deployment will become prohibitively large. Energy efficiency and sustainable solutions are the prime considerations for 5G wirelss networks. 5G wireless access networks will need to combine several innovative aspects of decentralized and centralized allocation looking for maximizing performance and minimizing signaling load.
