Abstract

An implementation of a baseband demodulator for DVB-T systems is presented. We build several multimode SIPs and integrate them into a DVB-T baseband demodulator. The demodulator includes FFT, channel estimator, channel equalizer, deinterleavers, FECs, and descrambler. We utilize Simulink to establish a system-level simulation environment and use this system simulation model to evaluate performance. Moreover, the modules we used to integrate the demodulator are multimode SIPs so that the demodulator is able to meet the multimode feature of not only DVB-T (2K and 8K modes) but DVB-H (4K mode) systems.
