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,...
The rate compatible punctured convolutional code (RCPC code) is an important module in Multi-band Orthogonal Frequency Division Multiplexing Ultra Wide Band (MB-OFDM-UWB) indoor positioning system introduced in this paper as a kind of useful channel coding to offer more protection against all kinds of channel noise under indoor channel environments. In this paper, RCPC code for MB-OFDM-UWB indoor...
