An efficient FFT (fast Fourier transform) processor is greatly needed for real-time operation in many OFDM applications, such as xDSL, DAB, DVB-T/H, and etc. This study developed four types of efficient memory-based Radix-2 FFT architecture with a memory size of N words for N-point FFT operations. The latency can be improved from (N/2)+(N/ 2)logN, to(More)
This paper presents a radix-2 memory-based FFT processors, namely, MBFFTP, with a memory size of N words for large N complex points, where each word contains 24 bits. The developed MBFFTP meets DVB-T standard and can handle both 2K and 8K modes in the same architecture. The processors have been designed and implemented in TSMC 0.18mum 1P6M process. Results(More)
Digital Video Broadcasting-Terrestrial (DVB-T) is a leading international standard established for the move from Analog to Digital Broadcasting basically via terrestrial networks. Within DVB-T, it is possible to carry defined data containers in addition to the audio and video in the MPEG-2 transport stream. This paper presents a hardware/software co-design(More)
