摘要

自适应调制和编码(AMC)是WiMAX系统在宽带无线接入(BWA)应用中的主要优势之一。该系统通过改变调制和编码来提供高质量的服务。这一功能对视频和图像传输等点播服务尤其有吸引力。系统物理层监测信道状况，估计接收信号的信噪比自适应变化。在本文中，我们评估了系统在图像传输方面的性能。我们在AMC中使用峰值信噪比(PSNR)因子，并与经典系统中使用导频随机信号的信噪比进行比较。

Adaptive Modulation and Coding in WiMAX system for optimum image transmission

Adaptive Modulation and Coding (AMC) is one of the main advantage of the WiMAX system in Broadband Wireless Access (BWA) applications. The system changes modulation and coding to provide high quality of service. This feature is especially attractive for services like on demand video and image transmission. The physical layer of system monitors the channel condition and estimating Signal to Noise Ratio (SNR) of received signals to change adaptively. In this paper, we evaluate the system performance for image transmission. We use Peak Signal to Noise Ratio (PSNR) factor in AMC and compare it with a classical system that uses signal to noise ratio for a pilot random signal.
