Packet Format Design and Decision Directed Tracking Methods for Filter Bank Multicarrier Systems

Packetized data transmission is commonly used in wireless communication systems. Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the channel impulse response or to adjust a set of channel equalizer parameters. In this paper, following the same philosophy, the authors develop a packet format for multicarrier systems that operate based on filter banks, Filter Bank Multi-Carrier (FBMC) systems. The related algorithms for carrier frequency and timing recovery as well as channel identification/equalizer adjustment and methods for carrier and timing tracking loops are proposed.
