In this paper, we propose a design method of Nyquist filter using fast successive projection accelerated by exponential prediction. First, we show an updating coefficient based on simultaneous approximation problem of frequency and time domain using successive projection method at the same time. And allowable error of successive projection is updated at each iteration. Next, we use an exponential prediction for accelerate a convergence of Projection Onto Convex Sets. Finally, we show about efficiency of the proposed method, as compared to conventional successive projection method.
