Receiver Architectures for 5G: Current Status and Future Prospects Amitesh Kumar, Brajendra Singh Sengar, Shalu Chaudhary, Saurabh Kumar Pandey, Sushil Kumar Pandey, Md. Hasan Raza Ansari, and Aaryashree Abstract In this chapter, the recent progress in receiver architecture and various aspects of the available receiver architectures have been discussed. Besides, an overview of the systematic classification of architecture has been analyzed. Docu- mentation of new possibilities and system-level trade has been closely inspected. Certainly, there is a requirement of low-power, flexible, and high-performance receiver architecture for the successful implementation of the 5G network. Different works in this regard have been considered as examples for discussing the status and prospects of architectures with respect to 5G future. Various architectures considered in this chapter can be very valuable to design 5G network in future and will expose the research community with new possibilties to explore for further improvements.
