- Abstract
- Orthogonal frequency division multiple access (OFDMA) and Single carrier frequency division multiple access (SC-FDMA) systems are new systems, which have become a preferred choice for current and future wireless communications. This is attributed to their advantages such as the use of frequency domain equalizers. In this paper, the issue of the wireless image transmission over OFDMA and SC-FDMA systems is investigated over a frequency selective channel for different modulation and subcarriers mapping schemes. Experimental results show that efficient wireless image transmission over OFDMA and SC-FDMA systems is possible. It is found that the interleaved systems greatly enhance the clarity of the received image and their performances are better than that of the localized systems. Results also show that the SC-FDMA system provides better performance than the OFDMA system when the 16QAM modulation scheme is used and a worse performance than the OFDMA system when the QPSK modulation scheme is used.
