Realization of digital coherent receivers

2009 IEEE LEOS Annual Meeting Conference Proceedings, 2009
The hardware architecture of digital coherent optical receivers supporting ≫40 Gb/s data rates and general considerations about signal processing algorithms are presented as well as a chipset layout for a 40 Gb/s digital coherent polarization-multiplexed QPSK receiver.

Research and Implement of Digital Receiver

2010 International Conference on Signal Acquisition and Processing, 2010
In order to detect weak signal in complex background, the paper studies and realizes six-channel digital receiver. Receiver is designed as much digital structure as possible, the basic hardware parameters of receiver can be adjust to meet different needs of specific applications by calling the corresponding software packages.

Digital TV receiver with a low IF

IEEE Transactions on Consumer Electronics, 1993
A TV receiver design that uses the quadrature-receiver principle is presented. Due to a low IF (intermediate frequency) of 2.6 MHz, normal video analog-to-digital (A/D) converters are sufficient to digitize the complete modulated signal. A lot of RF processing is done within the digital domain.

A digital multistandard paging receiver

IEEE Transactions on Consumer Electronics, 1999
Many different paging systems exist. Therefore it is very desirable to be able to implement the paging receiver in a way that all major paging standards can be supported. In this paper, a software radio receiver architecture which uses a signal demodulation technique based on a complex digital phase-locked loop is presented. This kind of software radio

A Novel Structure Digital Receiver

2018
This 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

Adaptive digital communication receivers

IEEE Communications Magazine, 2000
We present a tutorial review of adaptive signal processing applied to a digital communication receiver operating in a nonstationary environment. The topics covered include feedforward and recurrent neural networks and their applications to communication systems.

Digital Television Receiver for ISDB

Proceedings of the IEEE, 2006
This 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.
