An Improved Multilevel LINC Transmitter for Advanced Wireless Communication Systems

Beschreibung

Multilevel LINC Transmitter for Wireless Systems The goal of this work is to build a highly linear and energy-efficient multilevel LINC transmitter for wideband LTE applications.Excellent linearity with ACLR better than -45 dBc and EVM less than 8% should be achieved, in order to meet the most stringent linearity requirement for base station applications. The proposed transmitter architecture was implemented and measured. The results show over 50% energy efficiency while complying with requirements of 4G LTE downlink standard without using complicated DPD, hence reducing system complexity and power for wideband transmitters.
