IOP Conference Series: Earth and Environmental Science, 2019 Abstract The term sustainability is frequently associated with our future cities. However, in the most remote and unprivileged corners of the world off-grid systems have already established a new dimension for sustainability. With no infrastructure nor grid connections, off-grid systems offer a way to be self-sustainable and thrive with ...

A combined BP‐MF algorithm for wideband off‐grid DOA estimation with DP prior
Electronics Letters, 2022 Direction‐of‐arrival (DOA) estimation based on sparse Bayesian learning (SBL) framework has attracted extensive attention. The accuracy of on‐grid DOA estimation is restricted by the prescribed grid, while off‐grid approaches resolves the problem of grid
