An Implementation of Algorithmic and Hardware Design for OFDM Application
In advancing VLSI technology, OFDM has received a great deal of attention and been adopted in many new generation wideband data communication systems. In this paper the analysis of several FFT algorithms such as radix-2, radix-4, split radix and mixed radix 4-2 were designed using VHDL. The results show that the proposed processor architecture can greatly save the area cost while keeping a high- speed processing speed, which may be attractive for many real-time systems. By using the proposed structure, the proposed algorithm makes an offer the simple bit reversal mechanism which is only supported by a fixed radix FFT algorithm.
