Figure 3From: Amplitude PDF Analysis of OFDM Signal Using Probabilistic PAPR Reduction MethodSymbol Error Rate (SER) comparison between the analytical approach (line) and the simulation results (marker) over AWGN channel (red) and frequency-nonselective slowly fading channel (blue), where the data is QPSK modulated, and 1024-point FFT pairs are considered. The OFDM symbols are clipped at dB. In the figure, the lines represent our analytical approach, such as solid line (), dash line (), dot line (), and dash-dot line (). The markers represent the simulation results, such as (), □ (), ∆ (), × ().Back to article page
