摘要：
In this paper, we present physical and MAC layer techniques for high-speed wireless access to the Internet based on OFDM. Using dynamic packet assignment (DPA) for interference avoidance based on two examples of resource definition with different time and frequency units, we demonstrate that OFDM has significant flexibility to provide high transmission rates on demand with different available bandwidths. Innovations in radio link design, such as joint channel estimation and maximum likelihood decoding as well as interference suppression can be readily applied to coded OFDM systems. Significant performance gain in packet data throughput is realized in a system with aggressive frequency reuse.
