摘要
Orthogonal frequency division multiplexing (OFDM) is examined via digital computer simulation. Bit error performance of OFDM in a doubly spread channel is examined, and the effects of varying the guard interval and the number of carriers are demonstrated. The use of simulation as a design tool when doubly spread channel performance cannot be modeled mathematically is demonstrated. Simulations reveal that the designer has to strike a balance between the number of carriers and the guard interval in order to optimize performance and resource utilization.
