adaptation phy in audio and video
About the 10 Gigabit Ethernet Standard
White Paper 10 GbE Physical layer specifications (PHY) and supported media and reaches, as defined in IEEE 802.3 2005. The 10 GbE MAC operates at 10 Gbps at its service interface (towards PHY) and rate-adapts... [08 Feb 2008]
Adaptive Optimal Frame Length Predictor for IEEE 802.11 Wireless LAN
White Paper Link adaptation is one approach focusing on through building a reliable MAC and PHY layer to provide committed QoS. This paper presents an optimal frame length predictor in terms of maximizing the... [05 Dec 2007]
Joint PHY/MAC Based Link Adaptation for Wireless LANs With Multipath Fading
White Paper Thus, a cross-layer based design approach along with link adaptation is required to improve the network performance under different channel conditions. Wireless local area networks offer a range of transmitted data rates... [03 Sep 2007]
Experimental Evaluation of Application Performance With 802.11 PHY Rate Adaptation Mechanisms in Diverse Environments
White Paper This paper examines the impact of physical layer rate adaptation mechanisms on the performance of real applications over 802.11 wireless links in diverse channel environments. The paper considers two different and well... [01 Aug 2007]
IEEE 802.11 Rate Adaptation: A Practical Approach
White Paper Today, three different PHYsical (PHY) layers for the IEEE 802.11 WLAN are available (802.11a/b/g); they all provide multi-rate capabilities. While this rate adaptation algorithm is a critical component... [24 May 2006]
PER-Prediction for Link Adaptation in OFDM Systems
White Paper The physical layers (PHY) of modern wireless communication standards like HiperLAN/2 or IEEE802.11a provide a high degree of flexibility allowing the Data Link Control (DLC) layer to adapt various transmission parameters... [02 Nov 2004]
