Abstract-OFDM systems are currently being widely used in 4G and UWB communication systems. OFDM system consisting of IFFT and modulator increases the complexity of hardware implementation. In this paper, design and implementation of Autocorrelator and CORDIC algorithm for OFDM is discussed for optimized power and delay. Autocorrelator is used for frame detection and carrier frequency offset estimation. The CORDIC is used to estimate the frequency offset and to calculate the division in thedoi:10.7763/ijet.2011.v3.244 fatcat:skk3wax3qjhzledi2kr5re6rfi
