— One of the main concerns in ultra wide band (UWB) impulse radio (IR) technology is the presence of severe multiple access interference (MAI). Efficient receivers should theref...
— As an optical signal propagates along a lightpath to its destination in distributed wavelength-routed optical networks, the signal’s quality is degraded by transmission impai...
— This paper addresses soft estimation of time-varying frequency selective channels using Kalman smoothing. The proposed estimator uses soft extrinsic information provided by a c...
Randomized agreement protocols have been around for more than two decades. Often assumed to be inefficient due to their high expected communication and time complexities, they ha...
