A Practical Transmission System Based on the Human Visual Model for Satellite Channels
(1999)
This paper presents a practical architecture for joint source-channel coding of human visual model-based video transmission over a satellite channel. Perceptual distortion model just-noticeable-distortion (JND) is applied ...
A Carrier Frequency Estimation Method of MPSK Signals and Its Systolic VLSI Implementation
(1999)
In this paper we present an autocorrelation-based method for estimating the carrier frequency offset of an MPSK signal with random data modulation. Although autocorrelation-based techniques imply heavy usage of hardware ...
VLSI Implemented ML Joint Carrier Phase and Timing Offsets Joint Estimator for QPSK/QQPSK Burst Modems
(1999)
A high performance ASIC supporting multiple modulation, error correction, and frame formats is under development at Hughes Network Systems, Inc. Powerful and generic data-aided (DA) estimators are needed to accommodate ...
A Video Transmission System Based on Human Visual Model for Satellite Channel
(1999)
This paper presents a practical architecture for joint source-channel coding of human visual model-based video transmission over satellite channel. Perceptual distortion model just-noticeable-distortion (JND) is applied ...
Carrier Frequency Estimation of MPSK Modulated Signals
(1999)
In this paper we concentrate on MPSK carrier frequency estmation based on random data modulation. We present a fast, open-loop frequency estimation and tracking techinque, which combines a feedforward estimator stuctureand ...
VLSI Implemented Data-Aided ML Parameter Estimators of PSK Burst Modems
(1999)
A high performance Universal Modem ASIC that supports several modulation types and burst mode frame formats is under development. The ASIC is designed to work under stringent conditions such as large carrier frequency ...
A Video Transmission System Based on a Human Visual Model
(1999)
This paper presents a joint source-channel coding scheme of digital video broadcasting over satellite channels. The video compression is based on a human visual model. A perceptual distortion model, the just-noticeable-distortion ...
On the True Cramer-Rao Lower Bound for the DA Joint Estimation of Carrier Phase and Timing Offsets
(2000)
The Cramer-Rao lower bound (CRLB) plays a pivotal role in parameter estimation theory, such as timing, frequency and phase synchronization. Therefore, it receives considerable attention in the literature. This paper concerns ...

(1999)
A high performance Universal Modem ASIC that supports several modulation types and burst mode frame formats is under development. Powerful and generic data-aided (DA) parameter estimators are necessary to accommodate many ...
