The terrestrial digital video broadcast (DVB-T) system, specified in the ETSI
300-744 standard, is currently the most popular digital television system with
more than 120 million receivers deployed globally in integrated television
sets, set-top boxes, in-car modules, universal serial bus (USB) sticks, and
personal computer (PC) cards. A provider of multimedia application specific
integrated circuits (ASICs) in Asia required a DVB-T demodulation core as
part of its strategy to broaden its stake in this growing market. To meet this
challenge, Bell Labs partnered with Cambridge Industries Group, China, to
form an international team to design and implement the underlying
multimode orthogonal frequency division multiplexing (OFDM)based
receiver. This paper presents insight into the essential elements of the system
design, the design methodology, and project management and describes the
underlying signal processing algorithms, the bit accurate model, and register
