In the last few years, wireless scheduling algorithms have been proposed by supplementing wireline scheduling algorithms with a wireless adaptation scheme. However, QoS bounds have either been derived for flows that perceive error-free conditions, or a static worst case channel condition. Such an assumption of the channel condition is unrealistic since channel errors are known to be bursty in n...

Prior to recent advances in computational electromagnetics, a deterministic timedomain simulation of a wireless channel was deemed too expensive to implement. Conventionally, wireless channel designers use more practical measurement-based techniques, involving statistical models or channel transfer functions [1–3]. However, despite their convenience, such techniques can be inaccurate and lead t...

IEEE 802.11n is a newly emerging wireless standard which, relative to former 802.11 protocols, such as 802.11a/b/g, has a number of new mechanisms that enable multifold increases in transmission speeds. These new mechanisms include multipleinput-multiple-output (MIMO) transmission schemes as well as the option for channel bonding two 20MHz channels into a single 40MHz channel. Furthermore, 802....

The characteristics of wireless communication channels may vary with time due to fading, environmental changes and movement of mobile wireless devices. Tracking and estimating channel gains of wireless channels is therefore a fundamentally important element of many wireless communication systems. In particular, the receivers in many wireless networks need to estimate the channel gains by means ...

For wireless channels, interference mitigation techniques are typically applied at the bit/packet transmission level. In this short paper, we present a simple channel predictor that responds to impairments that are present at the packet transmission time scale. A channel predictor determines whether to transmit a packet or not depending on the state of the wireless channel. Channel state inform...
