Latest Patents

David holds a patent for a "Receiver for and method of receiving symbols over time varying channels with Doppler spread." This invention introduces a near-optimal Karhunen-Loeve basis expansion modeling (KL-BEM) orthogonal time frequency space (OTFS) receiver with superimposed pilots. The proposed method allows for high-mobility communications in environments with Doppler spread channels. The process begins with an initial KL-BEM channel estimation using superimposed pilots, followed by the removal of these pilots from the received OTFS signal. The equalization is achieved through a message passing (MP) algorithm. The detected data symbols are then utilized as pseudo pilots to refine both KL-BEM channel estimation and equalization iteratively. Simulation results demonstrate that this KL-BEM OTFS receiver outperforms prior technologies in terms of mean-square-error (MSE) of channel estimation and bit error rate (BER). It also approaches the BER lower bound achievable with perfect channel estimation, contributing to high spectral efficiency and rapid convergence performance.
