Abstract :
The effect of the transmitter gain transient when the power-amplifier is switched on and off (to conserve battery power) is investigated for OFDM systems. A simple receiver-side correction technique is proposed for the HIPERLAN/2 OFDM system, and the improvement in performance is demonstrated.
