STF block code is concatenated with channel coding namely convolutional code of rate 1/2 with length 5 to further combat channel impairment. The coded STF scheme is compared to ST-OFDM and SF-OFDM over IEEE 802.11 multipath channel at delay spread of 700 ns and 1 ms in outdoor environments. Results show that Coded STF-OFDM scheme outperforms other schemes by as much as 8 dB (against ST-OFDM) at 700 ns delay spread. The scheme also outperforms others at longer delay spread but is almost comparable to coded SF-OFDM. 2011-09-13T00:28:05Z 2011-09-13T00:28:05Z 2007-03 Article The Journal of the Institution of Engineers, Malaysia, vol. 68(1), 2007, pages 10-15 0126-513X http://myiem.org.my/content/iem_journal_2007-178.aspx http://hdl.handle.net/123456789/13716 en The Institution of Engineers, Malaysia
