Latest Patents

Among his latest patents is a method and system for compressed sensing joint channel estimation in a cellular communications network. This innovation involves methods and systems for performing compressed time domain joint channel estimation in a multi-user MIMO wireless network. The process includes receiving data corresponding to the transmission of training signals from multiple users to a base station over a MIMO wireless network. It also entails determining a limited data set by restricting the received data in a time domain based on an estimated maximum delay spread. Furthermore, it involves forming a well-conditioned low rank training matrix by identifying a channel model, estimating an active tap from this matrix, and subtracting the contribution of the selected active tap from the limited data set.

Another notable patent by Dhakal focuses on similar methodologies for compressed sensing joint channel estimation. This patent outlines the steps of receiving training signals from various users, estimating a maximum delay spread for the received data, and limiting the data in the time domain to this estimated maximum delay spread. The process includes selecting and estimating an active tap from the limited data set and subtracting its contribution from the reduced data set. These steps can be repeated until the residual signal falls below a specified minimum, ensuring accurate channel estimation.
