Exploring underused spectrum bands such as the mmWave band is key to solve future wireless communications necessities. This work studies the problem of channel estimation in multi-antena systems in this high-frequency band considering the few propagation parameters that are unveiled due to the sparse propagation nature. We address the channel estimation by applying atomic norm as a gridless multidimensional spectral estimation. The applied methodology is compared in different scenarios with several on-grid spectral estimation approaches and also with traditional non-parametrical methods.
