Equalization digital on-channel repeater in the single frequency networks
TLDR
Equalization DOCR (EDOCR) is introduced which regenerates the original 8-VSB output signal with relatively short time system processing delay and can eliminate the loop-back signal up to 5.5 dB with 5 /spl mu/s system processing Delay.
Blind decision feedback equalization for VSB-based DTV receivers
We present a novel blind decision feedback equalization algorithm for VSB-based DTV receivers by modifying a stop-and-go dual-mode algorithm to improve the performance of convergence speed and
Performance analysis of error propagation effects in the DFE for ATSC DTV receivers
TLDR
It is found that while blindequalization is preferable to decision-directed (DD) equalization at signal-to-noise ratio (SNR) values less than 18 dB, DD equalization is superior to blind equalizer at SNR values greater than 18dB.
An adaptive carrier synchronization technique for robust 8-VSB DTV reception
The proposed carrier synchronization technique not only provides a robust 8-VSB DTV reception in fixed and indoor environments, but also makes it possible to watch HDTV in the portable environment.
Analysis on Channel Estimation for the Equalization in ATSC DTV Receivers
TLDR
Analysis results on finite-impulse response (FIR) channel estimation used for the equalization in Advanced Television Systems Committee digital television receivers show that the adaptive FIR channel estimator provides an unbiased estimation and matches well its corresponding channel coefficients irrespective of the number of taps of the estimator and the non-causality of the unknown channel.
A Design of Equalization Digital On-Channel Repeater for Single Frequency Network ATSC System
TLDR
The designed EDOCR can produce an exact replica of the main transmitter's signal with high SNR although there may be adjacent channels and input signal is distorted by multipath and noise.
Performance improvement of a decision-feedback equalizer in terrestrial dtv receivers by reduction of error propagation
TLDR
A novel equalization method for ATSC terrestrial digital televi.sion (DTV) receivers by incorporating a channel-matched filter (CMF) and an intelligent slicer and simulation results show that the proposed method is more efective and more stable than exi.
Field Test Results of the E-VSB System in Korea
TLDR
The field test results show that the E-V SB system does not only outperform the 8-VSB system at severe multipath environment such as indoor reception, but also is fully backward compatible with it.
A novel modulator for equalization digital on-channel repeater in ATSC system
TLDR
A novel modulator for the equalization digital on-channel repeater (EDOCR) in ATSC system uses equi-ripple VSB filter instead of conventional square root raised cosine (SRRC) filter and satisfies FCC RF emission mask.
Digital beamforming algorithms for the VSB DTV receiver system
TLDR
The paper proposes digital beamforming algorithms for vestigial sideband (VSB) based digital TV (DTV) receivers that can improve the overall system performance matching with other parts in the simulation, and demonstrates the performance of the proposed system under the Brazil channel model.
