This paper proposes a FFT processor design for DAB and WiMAX applications whose efficiency is improved in terms of performance. The design is optimized for power. The 2D 256 point FFT employs Radix-16 algorithm which significantly minimizes the number of complex computations. The architecture is pipelined, with 10 bit real and imaginary inputs. The proposed pipelined FFT architecture has the advantage...
Multiplication of the data with several constants forms the basis for many Digital Signal Processing (DSP) and multimedia applications like in Digital Filtering, in Image Processing DCT and DFT. Most portable devices or handheld devices such as MP3 players, mobile phones, DSLR etc involves large number of multiplications with the several constants. FFT processors also involve large number of complex...
