Abstract :
A complete modem ASIC has been designed at Nokia Research Center, Bochum, to meet IEEE 802.11 a Physical Layer requirements. This paper gives an overview of the implemented synchronization algorithms, i.e. packet detection, frequency synchronization and fine-timing synchronization. Especially the optimization of these algorithms for an area- and power-efficient design and the resulting architecture are pointed out.
