Power amplifier linearisation scheme to mitigate superfluous radiations and suppress adjacent channel interference

Power amplifiers are one of the costly devices in wireless communication systems and exhibit non-linearity. The problem of non-linearity in the power amplifier categorises in two disturbance impacts, output distortion and in-band distortion which lead to adjacent channel interference and constellati...
