EXPLORING THE CAPABILITIES OF RECONFIGURABLE HARDWARE FOR OFDM-BASED WLANS

摘要

In this paper, the potential of reconfigurable hardware in wireless communication systems is evaluated. As most of the published works aim at the usage of reconfigurable architectures as a universal platform for different standards, the optimization capabilities of reconfiguration techniques for hardware modules within one standard are often not considered. This work focuses on the hardware optimization within one transmission scheme, namely OFDM (Orthogonal Frequency Division Multiplexing). By making use of special characteristics of packet-based WLANs and standard specifications, functional blocks of an OFDM receiver can be mapped on the same hardware. Even performance enhancements can be achieved without any additional hardware.
