Abstract :
We consider the performance of space-time trellis codes in orthogonal frequency division multiplexing systems (STTC-OFDMs) over quasi-static frequency selective fading channels in this paper. In particular, the effect of channel delay distributions on the code performance is investigated. The performance of the STTC-OFDMs under various channel conditions is evaluated by simulations. It is shown that the simulation results agree with the analysis.
