This paper presents the interference scenario and describes the benefits and tradeoffs of band shifting to the IEEE 802.11a 5GHz UNII (Unlicensed National Information Infrastructure) spectrum.

CCX has now been added to the Motorola Fusion WLAN supplicant; complementing the existing portfolio of “Mot-on-Mot” standards-plus features. This paper provides a technical overview of the CCX program and its capabilities.

The PAPR reduction weights are applied on each subcarrier in the frequency domain and are designed to either be fixed over a group of subcarriers (in addition to multiple bauds) or the weights are parameterized by time taps. The advantage of these methods is to simplify channel estimation by not destroying the channel frequency correlation (for weights fixed over groups of subcarriers) or by increasing the effective length of the channel to be estimated (for the weights parameterized by timetaps). Simulation results show up to a 6.0 dB decrease in PAPR where PAPR is measured over an OFDM baud.

We present uWave, an efficient recognition algorithm for such interaction using a single three-axis accelerometer. Unlike statistical methods, uWave requires a single training sample for each gesture pattern and allows users to employ personalized gestures and physical manipulations. We evaluate uWave using a large gesture library with over 4000 samples collected from eight users over an elongated period of time for a gesture vocabulary with eight gesture patterns identified by a Nokia research. It shows that uWave achieves 98.6% accuracy, competitive with statistical methods that require significantly more training samples. Our evaluation data set is the largest and most extensive in published studies, to the best of our knowledge. We also present applications of uWave in gesture-based user authentication and interaction with three-dimensional mobile user interfaces using user created gestures.
