Abstract :
This paper presents space-time coded orthogonal frequency division multiplexing (OFDM) systems with multiple transmit antennas. We combine space-time codes and OFDM techniques in frequency selective fading environments. In this paper, we compare orthogonal block codes and quasi-orthogonal block codes with 4 transmit antennas. Also, a capacity analysis is presented in OFDM systems.
