Embrace Circuit Nonlinearity to get Transmitter Linearity and Energy Efficiency

DML 2013-2015 Earl Mc Cune

Besser Associates, 2383 Pruneridge Ave, Santa Clara, California, 95050, USA

Wireless communications signals have evolved greatly over the past century, from the use of Morse Code to very complicated digital modulation schemes such as wideband CDMA (WCDMA) and 3GPP Long-term evolution (LTE). This progression challenges the design of transmitters to be simultaneously...


What's New in Digital Pre-Distortion

DML-E 2015-2016 John Wood

In cellular wireless communications systems, the RF power amplifier (PA) in the transmitter must be as efficient as possible, to minimize energy costs, to prolong battery life, and for ‘green’ considerations.  Modern spectrally-efficient, digitally-modulated signals such as LTE...
