Nowadays, serial communication is used in many high-speed communication situations instead of parallel communication. In high-speed serial communications, data recovery is an important and difficult part, which directly determines the success or failure of communication. This paper presents a FPGA-based data recovery method for high-speed serial signal. First, each bit of serial signal is over-sampled...
This paper presents an implementation of DisplayPort 1.1 Link Layer. The DisplayPort link layer provides isochronous transport service, link service, and device service. Isochronous transport service in source device maps the video and audio streams into the main link under a set of rules, so that the stream can be properly reconstructed to original format and synchronized by the sink device. The...
We propose QUEST (QUality ESTimation), a new method that accurately estimates IEEE 802.11 wireless link quality with no in-band signaling overhead. Existing link quality estimation methods either are based on hello exchanges by fixing or varying transmission rates or rely on the history (e.g., delivery ratio) of previously sent data packets in a per-rate/-neighbor manner. QUEST on the other hand,...
