Abstract :
Mobile video services have generated a lot of interest recently. To reach a cost-effective solution, design trade-offs among system performance, hardware complexity, and power consumption must be considered in the early design phase of such applications. In this article, we present a system overview, simulation platform, and hardware design of a DVB-T/H baseband receiver. Starting with a design platform, several algorithms on both inner and outer receivers are developed to meet target system performance under different channels. Then, system architecture and related key modules are explored, taking into account both silicon area and power consumption. Finally, several design issues related to the integration of the proposed DVB-T/H inner and outer receivers are addressed.
