Bandlimiting Polar Signals with Special W-CDMA Constellations

Abstract

The polar transmitter concept promises significant higher power efficiency utilizing nonlinear power amplifiers. RF transmitters using polar transmitter technique are currently available for EDGE systems and are under development for UMTS. The UMTS extensions HSDPA and HSUPA provide a number of additional physical uplink channels which can lead to a variety… (More)
