In this letter, a switched transmission technique is presented that can provide the orthogonal frequency division multiplexing (OFDM) systems with additional diversity gain. The space-time block coding (STBC) and space-frequency block coding (SFBC) a

Previous research has identified two efficient and complementary diversity techniques for OFDM: space-time and space-frequency block coding (STBC/SFBC). Each coding scheme is known to be stronger than the other under certain channel conditions. For l

Orthogonal frequency division multiplexing (OFDM) with space frequency block code (SFBC) outperforms OFDM with space time block code (STBC) in the fast fading channel environment. However, a complex orthogonal code with code rate one does not exist f
