Abstract :
In this paper, we discuss the available transmitter architectures in a Software Defined Radio (SDR) context and present a suitable polar architecture implementation under three different modulation formats (TETRA, EDGE and CDMA2000FW). Then, we show how its recognized nonlinear impairments can be overcome using appropriate digital amplitude and phase pre-distortion algorithms.
