Orthogonal Frequency Division Multiplexing and Fast Fourier Transform

[[abstract]]The FFT can be applied for synthesizing the carriers that are orthogonal and spaced in frequency at the symbol interval to transform the transmission in the Orthogonal Frequency Division Multiplexing system. The proposed FFT processor would be implemented with 32-bit complex data precision based on radix-4 butterfly structure with DIF-FFT algorithm. The proposed processor computes a 1024-point FFT takes 64.3 μs while frequency is 20MHz that has close performance to pipelined architectures and smaller area, for being not used enormous multipliers, than pipelined architectures.[[fileno]]2030110030022[[department]]電機工程學
