Abstract :
This paper studies the performance of a broadband OFDM system concept intended for fixed and nomadic applications. The system is designed for efficient packet data transmission, and in particular for TCP/IP. A combination of OFDM, adjustable time division duplexing (TDD), adaptive modulation/coding, and selective ARQ is used to provide a flexible and robust air interface. Estimates of the achievable data rates and spectral efficiencies under different deployment scenarios are obtained from a combination of link-level and system-level simulations
