Implementation of energy efficient partial FFT processor for wireless communication system

Abstract

The Processor which is widely used in the orthogonal frequency division multiple access (OFDMA) communication system is the Fast Fourier Transform. To improve the transmission performance in OFDMA system, resource allocation is implemented. In this context, we designed and found the partial cached Fast Fourier Transform Processor which satisfies the purpose for the distribution of allocation resources to the user of the OFDMA system. We designed 128 point partial cached FFT Processor. This paper presented by using energy efficient partial FFT processor for wireless communication systems.
