Abstract
In this paper we present a modification of the interplex scheme, which allows to increase the power efficiency. The proposed method consists in introducing a constant time offset for each signal component, in order to maximise the power at the output of the receive matched filter. With the chosen high power amplifier (HPA) setup, this technique improves the receive power efficiency by 2-3% without any change in the transmitter/receiver hardware.
