An efficient Fast Fourier Transform (FFT) processor is greatly needed for real-time operation in many OFDM applications, such as xDSL, DAB, DVB-T/H, and etc. This paper presents a low-cost Parallel Memory-based FFT (PMB-FFT) processor for DVB-T2 applications. The processor has been designed and implemented in 90nm 1P9M CMOS process. Experimental results show that the PMB-FFT processor meets the DVB-T2 standard with N=32,768 points, and takes only 2.51 mm(2) in the core area with a power consumption of 0.89 mW at 25MHz.
