A low-complexity method of linearly combining an analog frequency-modulation (FM) signal with a low-level multitone signal for simultaneous broadcasting of digital data and analog FM is proposed an
This paper analyses the interest of digital beamforming (DBF) for various reference missions, covering multimedia applications.
In this paper we describe a theorectical framework for obtaining a detailed characterization of the analog properties of a mixed signal transmission channel and present experimental results for the
This paper provides a theoretical basis for eliminating or reducing the energy consumption due to transients in a synchronous digital circuit.
Digital Coding of Speech in Sub-bands By R. E. CROCHIERE, S. A. WEBBER, and J. L.
Preface: Digital Coding is by no means a new subject. It has been practiced for the better part of fifty years, with the last twenty years, witnessing an unprecedented amount of activity.
Conventional coherent detection attempts to synchronize local lasers with transmit lasers indiscriminately without considering individual noise contributors.
We demonstrate the use of digital coherent superposition to improve the performance of space-division-multiplexed (SDM) 676-Gb/s OFDM-16QAM superchannels, achieving ~4 dB improvement in OSNR by usi
