Electronics Project: VLSI Implementation of High Speed and High Resolution FFT Algorithm Based on Radix 2 for DSP Application

This paper concentrates on developing FFT and IFFT. IFFT/ FFT are complex and main blocks of OFDM system also it consumes many resources so new technique is proposed in which FFT/IFFT is implemented in such a way that it consumes very less resources. The work also includes in designing a mapping module, serial to parallel and parallel to serial converter module. All modules are designed using VHDL programming language and implement on Spartan 3e designer kit.
