Latest Patents
One of Rizwan's latest patents focuses on data detection in MIMO systems with demodulation and tracking reference signals. This patent discloses a method for wireless communication that involves receiving a wireless communication via a receiver of a mobile communication device. The process includes deriving a demodulation reference signal from a first plurality of symbols of the wireless communication, creating a channel estimation matrix using this signal, and inverting the matrix to obtain a channel pseudo-inverse matrix. Additionally, it involves deriving a tracking reference signal from a second plurality of symbols, calculating a phase shift for additional symbols based on the tracking reference signal, and determining a corrected channel pseudo-inverse matrix for these symbols. The receiver is then controlled to accomplish data detection using the corrected matrix on one or more orthogonal frequency division multiplexing subcarriers.
