PAPR Reduction in OFDM Systems using Adaptive Active Constellation Extension Algorithm
OFDM Signal combines the multiple symbol representations method with a signal clipping method using a new hybrid PAPR reduction technique. The amplitude of the signal is limited to the threshold value using clipping method which considering the signal must be interpolated before A/D conversion and also different filtering technique has been proposed. The clipping technique has the subcarriers h...
