Abstract: Digital predistortion has been proved to be an effective remedy for the nonlinear distortion in radio-frequency power amplifier. Unfortunately, conventional digital predistorters (DPDs) developed for single-band transmitters can not be directly applied to concurrent dual-band.… read more here.

DOI: 10.1109/access.2018.2802928
Abstract: Recently, Celik et al. proposed a lookup-table (LUT)-based embedding mechanism for spread-spectrum watermarks, in which the content distribution server sends an encrypted content to the client, then the client uses his or her personalized decryption… read more here.

DOI: 10.1109/tcsi.2020.3004521
Abstract: In all-digital transmitters (ADTs), delta-sigma modulation (DSM) is the most popular encoding method. However, implementing DSM-ADT on a field-programmable gate array (FPGA) produces problems with high complexity and low carrier frequency (CF) agility. To solve… read more here.
