In this paper, a fast search-free method for direction-of-arrival (DOA) estimation with coprime arrays was proposed. It is based on the use of methods that operate on the uniform linear subarrays of the coprime array and that enjoy many proces

In this paper, we firstly construct a wide-band undersampling array, then present a novel frequency and direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz). Choosing a set of appropriate sampling frequencies and

describe the compressive sensing to be applied into the wireless communication
