An Adaptive Loop Canceller for Relay Stations in Digital Terrestial Broadcasting Systems.

An Optimal Gain Control Scheme for Digital On-Channel Repeater with Feedback Interference Canceller in Digital Terrestrial Television Broadcasting Networks

In this paper, a new gain control scheme is proposed for a digital on-channel repeater (DOCR) with a feedback interference canceller (FIC) in Digital Terrestrial Television Broadcasting (DTTB) networks. In the proposed scheme, a variable attenuator is placed behind the amplifier of the DOCR and the least mean square (LMS) adaptive algorithm is implemented in the FIC to estimate the feedback cha...

An Efficient Hierarchical Modulation based Orthogonal Frequency Division Multiplexing Transmission Scheme for Digital Video Broadcasting

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

VLSI Implementation of an Adaptive Noise Canceller

Adaptive Noise cancelling is a speech-specific filtering technique to suppress additive interference. It is a sensible choice for speech-orientated devices in situations where the designer has no knowledge of the properties of interference that could potentially corrupt the input speech to a point beyond intelligibility. A good example of devices subject to such noise is mobile telephones, wher...

A Metadata-Based Environment Adaptive Review System for Digital Broadcasting

In this paper, we propose the broadcasting data structure that can clip the requested scene or information in the TV program, and that can reconstitute the TV program depending on review environment or the purpose. As a result, this mechanism enables users to use the clipped broadcasting contents for various purposes.
