Digital broadcast systems have increasingly been deployed for various services such as Digital Video Broadcasting (i.e. DVB-S, DVB-T, etc.) and Digital Audio Broadcasting (DAB). Classical digital broadcast systems were designed with fixed modulation guarantee reliable communication even with very hostile channel environment. DVB-T2 terrestrial television standard is becoming increasingly import...

Digital Video Broadcasting-Terrestrial (DVB-T) is the most widely deployed digital terrestrial television system worldwide with services on air in over thirty countries. In order to increase its spectral efficiency and to enable new services the DVB consortium has developed a new standard named DVB-T2. A nearly definitive specification has already been published as a BlueBook as well as an impl...

This study presents the evaluation of digital video broadcasting-terrestrial second generation (DVB-T2) Television signal quality in Jos using Integrated Services Limited signal. The delivery remains problematic Nigeria due to attenuation and degradation between transmitter receiver station. is primarily environmental atmospheric perturbations prevalent along paths. research aim determine DVB-T...

In this paper we describe the potential of multi-antenna techniques (MIMO) in the context of digital video broadcasting (DVB) systems. DVB standards have been challenged by the increasing demand of high data rate applications and larger indoor coverage area. MIMO is a key technology to increase the system capacity and link reliability without any additional bandwidth or transmit signal power. T...

This letter presents the C/N requirements for DVB-T2 fixed reception. Results have been obtained from field trials carried out to test DVB-T2 performance, considering outdoor rooftop antenna scenario. Two commercial receivers have been used to obtain C/N threshold values for image error-free condition. The tested configuration modes are the ones recommended for this scenario: 32K FFT and 64 and...

This paper suggests an improved integer frequency offset (IFO) estimation scheme using P1 symbol for orthogonal frequency division multiplexing (OFDM) based the second generation terrestrial digital video broadcasting (DVB-T2) system. Proposed IFO estimator is designed by a low-complexity blind IFO estimation scheme, which is implemented with complex additions. Also, we propose active carriers ...

Digital terrestrial video broadcasting systems based on orthogonal frequency division multiplexing (OFDM), such as second generation of digital standard (DVB-T2), often include carriers reserved for peak-to-average power ratio (PAPR) reduction. This paper presents a low-complexity PAPR reduction method that inserts coded data onto subset carriers. Using differential binary phase shift keying (D...

This White Paper provides an overview of major techniques used in DVB-T2 and their impact on service planning and operation of this new transmission technology.
