Abstract

In this paper we present 4 transmit and 1 receive (4Tx:1Rx) antenna system of coded space-time-frequency in conjunction with orthogonal frequency division multiplexing (Coded STF-OFDM). We concatenate STF block code with channel coding namely convolutional code of rate 1/2 with length 5 to combat channel impairment. We compare our coded STF scheme with ST-OFDM and SF-OFDM over IEEE 802.11 multipath channel under delay spread of 700 ns and I us in outdoor environments. Results show that Coded STF-OFDM scheme outperforms other schemes by as much as 8 dB (against ST-OFDM) in spread of 700 ns. The scheme also outperforms others over a severe channel with delay spread of 1 us but is almost comparable to coded SF-OFDM.
