Enhanced Core Processor Blocks of OFDM System

Provided by: International Journal of Electronics Communication and Computer Engineering Topic: Mobility Date Added: Sep 2011 Format: PDF
OFDM is a multi carrier modulation technique in which the carriers are Orthogonal to each others as a result of which it provides high bandwidth efficiency and multiple carriers share the data among themselves. This paper describes the design and implementation of Enhanced Core Processing Blocks of OFDM Transmitter and Receiver, i.e., the FFT and IFFT Blocks that can be easily ported to an FPGA or an ASIC. The methodology used is the 8-point IFFT/FFT DIF with radix-2. The design unit consists of a common pass module and multiple path modules for which the timing simulations have been generated using Altera Max plus II. Finally, the performance analysis of the implemented system has been done by comparisons with MATLAB Simulations.
