Design of a DVB-T/H compliant baseband receiver

In this paper, a baseband receiver compliant to the digital video broadcasting-terrestrial and handheld (DVB-T/H) standard is presented. Algorithms of mode detection, symbol timing detection, carrier frequency offset (CFO) estimation and compensation as well as sampling clock offset (SCO), and a 2k/4k/8k triple-mode FFT processor are addressed. In addition, to combat with new problems for mobile reception, we investigate the mobile channel estimator and inter-carrier interference (ICI)-cancelling equalizer. Functional simulations show the validity of these algorithms and system performance of the proposed receiver.
