DOI: 10.1109/jssc.2017.2777821
Abstract: This paper extends N-path filtering to the code domain by proposing code-modulated local oscillator signals. A correlator-based perspective of N-path mixer receiver (RX) is presented to demonstrate interferer-rejection and desired signal reception in a code-domain… read more here.

DOI: 10.1109/lcomm.2021.3135379
Abstract: In this letter, we provide a practical framework to resolve whether code-domain NOMA (CD-NOMA) is beneficial when integrated with massive MIMO systems. In order to realize this integration, first, we develop a novel code-beamspace wideband… read more here.
