In this paper, a novel online mutual coupling compensation algorithm especially tailored to uniform and linear arrays is presented. It is conceived to simultaneously compensate for mutual coupling and estimate the direction-of-arrivals (DOAs) of signals impinging on the array since the estimated calibration matrix can be embedded within any classical(More)
This paper proposes a novel iterative algorithm to compensate for mutual coupling in uniform and linear arrays. It is designed with the aim of simultaneously compensating for mutual coupling and estimating the DOAs of impinging signals on the array. An iterative alternating minimization technique based on closed form solutions is performed to estimate the(More)
Sensor nodes are small-size, low-cost embedded systems capable of local processing and RF communication. In a sensor network, nodes need to organize their operations to perform distributed sensing tasks, and need therefore to be time synchronized to a common reference. In this paper we present a time-synchronization approach for wireless sensor(More)
