OFDM, Transmitter, Flexibility, ASIC


To fully utilize the available spectrum for a wireless com munication system it is feasible to adapt to different sit uations on the channel. In this paper a flexible OFDM transmitter is presented together with basic theory behind OFDM transmission. It is shown that high flexibility can be obtained with a reasonable amount of additional hard ware. Part of the design, the FFT-processor, has already been fabricated and measurement results are presented.
