Performance evaluation of image transmission over MC-CDMA system using two interleaving schemes

Abstract

In the present time, there is a rapid increase in demand for faster and reliable transmission of multimedia data through wireless channels. When multimedia data specially an image is to be transferred through the wireless channel, image is highly degraded due to wireless channel errors such as fading, interference and bursty errors. Multi-Carrier Code Division Multiple Access (MC-CDMA) technique is considered as the most promising technique for efficient wireless data transmission. This paper presents the performance comparison of image transmission over MC-CDMA system with two interleaving techniques; Helical interleaving and chaotic interleaving. At the receiver, Linear Minimum Mean Square Error (LMMSE) equalization is employed. System performance is measured through Peak Signal-to-Noise Ratio (PSNR) and Root Mean square Error (RMSE) values. From results, it has been evaluated that MC-CDMA system having chaotic interleaving and LMMSE performs better instead of having helical interleaving for image transmission over wireless channels.

Efficient wireless transmission scheme based on the recent DST-MC-CDMA

“…The first contribution of this paper over that in [6][7][8][9] is that the idea of the interference cancellation is used in the proposed scheme and not used in schemes in [6][7][8][9]. The second contribution is that image transmission over a recent DST-MC-CDMA system is not studied in the literature.…”

“…Robust image transmission over CDMA channels was proposed and studied in [6]. Performance evaluation of image transmission over MC-CDMA system using two interleaving schemes was presented in [7]. Recently, an efficient image transmission based on the chaotic interleaving and MMSE equalizer over MC-CDMA system was suggested and investigated in [8].…”

“…Image and multi-media transmission with CDMA technology has attracted the attention of several researchers [6][7][8][9]. Robust image transmission over CDMA channels was proposed and studied in [6].…”

“…Color image transmission over MC-CDMA system was also investigated in [9]. In [6][7][8][9], the impact of the MAI is not taken into consideration. Image transmission over orthogonal frequency division multiplexing (OFDM) system has also attracted more attention in the literature [10][11][12][13].…”

Performance Evaluation of SC-FDMA Systems Using Wireless Images

“…Due to remarkable internet growth, image transmission has emerged as one of the high growth applications of wireless communication technology. Performance comparison of image transmission over MC-CDMA system with two interleaving techniques; Helical interleaving and chaotic interleaving is presented in [8]. In [9], the wireless image transmission over OFDMA and SC-FDMA systems is investigated over a frequency selective channel for different modulation and subcarriers mapping schemes.…”
