A Novel Structure Digital Receiver
2018This paper studies a novel structure digital receiver to demodulate signal with large frequency offset. When the carrier frequency offset is large, the matched filter will filter out part of the in-band signal, resulting in decrease of SNR and deterioration of BER. Different from traditional receiver structure, the novel receiver put a coarse frequency

Digital Television Receiver for ISDB
Proceedings of the IEEE, 2006This paper presents the digital high-definition television (HDTV) receiver for the ISDB system. It receives 8 phase shift keying (8-PSK) satellite broadcast and orthogonal frequency division multiplex (OFDM) terrestrial broadcast. It decodes the MPEG2 audio/video stream and converts the original HDTV picture to the various display formats.

On Linear Receivers for Digital Transmission Systems
IEEE Transactions on Communications, 1974Two main classes of receivers for data modems using linear modulation systems over time-dispersive channels have been investigated by many authors for both theoretical and practical purposes, 1) structure-constrained linear receivers, such as zeroforcing and mean-square-error tapped-delay-line equalizers, and 2) nonlinear receivers, such as decision ...

Monobit digital receivers for ultrawideband communications
IEEE Transactions on Wireless Communications, 2005Ultrawideband systems employ short low-power pulses. Analog receiver designs can accommodate the required bandwidths, but they come at a cost of reduced flexibility. Digital approaches, on the other hand, provide flexibility in receiver signal processing but are limited by analog-to-digital converter (ADC) resolution and power consumption.

6th International Conference on Radio Receivers and Associated Systems, 1995
The paper describes an experimental digital receiver (tuner) for wideband applications in the HF-band. The output from the receiver is an undemodulated digitised signal with 750 kHz of useful bandwidth. The 5 MHz sampling frequency is generous compared to the bandwidth. This relaxes the demands on the analogue components and gives us the possibility of

A Digital Receiver for Tone Detection Applications
IEEE Transactions on Communications, 1976A digital circuit suitable for detection of tones in signaling applications is described. The amount of hardware required for the realization of the circuit is shown to be quite small. The circuit may be used for both analog and digital input signals. For analog signals, the necessary A/D conversion becomes very simple.

IEEE Transactions on Aerospace and Electronic Systems, 1966
Digital computers have evolved to an active role as components in communication systems, performing such functions as data processing, executive and adaptive control, management of waveform, and antenna characteristic selection. At one time, the interface between communication equipment and data processing was clear.
