【 摘 要 】

The orthogonal frequency division multiple access (OFDMA) system is a well-known system, which has recently become a preferred choice for wireless communications. This is attributed to its advantages such as the use of frequency-domain equalisers. The issue of the wireless images transmission over the coded and the uncoded OFDMA systems is investigated and evaluated for different wireless channels, different modulation schemes and different subcarriers mapping schemes. Experimental results show that efficient wireless images transmission over OFDMA systems is possible even for mobile channel. Results also show that the coded interleaved OFDMA system provides better performance than the localised OFDMA system, regardless of the wireless channel or the modulation scheme used.
