Abstract :
Orthogonal frequency division multiplexing (OFDM) systems are sensitive to timing and frequency estimation errors, which cause inter-symbol-interference (ISI) and inter-carrier-interference (ICI), leading to degradation in the system performance. In this paper, optimized implementation of synchronization algorithm for cellular reuse-1 OFDMA systems, compatible with IEEE 802.16d/e wireless MAN standard on Analog Devices Incpsilas TigerSHARC processor is presented. This implementation reduces the cycle-count by 45% and on-chip memory requirement by 95%.
