Performance evaluation procedure for mobile DVB-T2 reception in urban environments

Abstract

This paper presents a procedure for testing the mobile reception performance of DVB-T2 in urban environments. The main goal of this procedure is to reduce and simplify the measurement and processing stages, which are especially critical in the non-stationary and heterogeneous conditions of urban mobile reception. This procedure is supported by field trials carried out by the authors in these environments. The paper is focused on the DVB-T2 standard, but the methodology is also applicable to other new digital broadcasting systems designed for mobile urban reception, such as T2Mobile or DVB-NGH systems.

Determination of DVB-T2 Signal Quality in Nigeria: A Case Study of Jos, Plateau State, Nigeria

“…The DVB-T2 system fulfilled technical functionalities mainly from DVB-T [10] and digital video broadcasting -satellite second generation (DVB-S2) [11]. The DVB-T2, system offers meaningfully enhanced performance in mobile channels and its coding schemes greatly outperforms the forward error correction (FEC) techniques used in DVB-T higher order constellation, 256-Quadrature Amplitude Modulation (QAM), which increases the spectral efficiency and bit rate [2]. The flexibility of DVB-T2 offers other configurable parameters that could provide numerous configuration modes, providing different levels of protection and bitrates for DVB-T2 signals that could increase the robustness of the signal optimize data transmission capacity, and some combinations can be chosen to balance between robustness and transmission capacity.…”

“…It allows the simultaneous transmission of multiple services with different configurations thereby producing different robustness and quality. This system permits new type of reception scenarios for digital terrestrial signals, like mobile and handheld pedestrian reception scenarios, so DVB-T2 can be used for providing fixed outdoor, handheld, indoor and mobile services within the same channel due to the number of configurations supported [2]. The main goal of DVB-T2 standard is to achieve more bandwidth compared to DVB-T, targeting high definition Television (HDTV) services, improve single frequency networks (SFN), providing specific service targeting robustness, and services for fixed and portable receivers with 50% capacity throughput improvement compared to DVB-T [3].…”

Estudio y análisis de la propagación de las señales de Televisión Digital DVB-T en la ciudad de Panamá

“…Los resultados de las mediciones deben ser geolocalizados para tener un registro de la medición en la ruta que se establece la misma, y con estos valores registrados lograr establecer correspondencia entre la muestra recopilada y los puntos ubicados. Para tal efecto se utiliza un GPS sincronizado con una laptop y el equipo de recepción de señales en las bandas de operación del servicio de DVB-T. A esta técnica de medición se le denomina método Drive Test (Berjon-Eriz et al, 2011).…”
