Abstract

This paper presents the performance of the quadrature modulation (QM) transmitter when compared with the (PM) transmitter. So as to evaluate the substantive power efficiency in both transmitters, the effective demodulation power efficiency (EDPE) is proposed as a novel figure of merit for transmitters. Computer simulation reveals that the EDPE for a QM transmitter is lower than that for a PM transmitter. In addition, D/U for a QM transmitter is higher than the one for PM transmitter due to lower quantization noise. As a result, the EVMs for a QM transmitter is higher than the one for a PM transmitter.
