Linearization Implementation Challenges and Techniques for 5G Waveforms
With upcoming emergence of 5G communication, the criterion on RF front-end has become stringent. Some significant challenges are supporting MIMO, multiband, broadband communication with cost as well as energy efficient operation while maintaining linearity. Fulfilling such arduous requirements results in novel implementation challenges. This workshop lecture will focus on implementation challenges of (1) stand-alone ultra-wideband linearization solutions (up to 500MHz bandwidth for sub 6GHz communication band) (2) linearizer for high order MIMO transmission with system size, system cost and digital processing cost considerations with implementation example of 8×8 MIMO (3) and limitations of and solutions for utilizing low-cost hardware front-end.
