Efficient design for VLSI Architecture using OFDM

Lalit Mishra, Chandrakant Mishra, Sweta Singh

Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a system where data bits are transfer with multiple carriers and coded into a multiple sub carrier at transmission stage. Fast Fourier Transform (FFT) is widely used for operations in the field of digital technology. Some of the applications of the fast Fourier transform are as Signal analysis, Data compression, Image filtering, error free communication etc. Fast Fourier transform (FFT) is effectively use in the discrete Fourier transform (DFT). This paper is presented the design of an OFDM Transmitter including inverse fast Fourier transform (IFFT), mapping (modulator), serial to parallel and parallel to serial converter by using VHSIC Hardware description language (VHDL). The timing simulation and synthesized results are performed and analyzed by using Xilinx ISE Project Navigator: 6.2i.

Keywords: FPGA, OFDM, QAM, FFT, IFFT, DFT, VHDL, Communication, Power
