Receiver sensitivity is one of the most important parameters in determining the overall performance of a communication system. Industry has been using exhaustive search in a specified range to identify the achieved receiver sensitivity for wireless devices. Such an exhaustive search scheme is neither efficient in terms of measurement time, nor accurate due to the fixed stepsize. In this paper, we...
Database-aided user association, where users are associated with data base stations (BSs) based on a database which stores their geographical location with signal-to-noise-ratio tagging, will play a vital role in the futuristic cellular architecture with separated control and data planes. However, such approach can lead to inaccurate user-data BS association, as a result of the inaccuracies in the...
We consider the problem of estimating the intensity map of a spatially random phenomenon over a geographical area observed by a sensor network. The spatial phenomenon of interest is modeled using a Gaussian random field specified by its nonlinear mean and covariance functions. Our proposed algorithm includes two stages: a novel greedy sparse recovery algorithm to estimate the parameters of the mean...
