Abstract: The newly developed 2nd generation standard for digital video broadcasting (DVB-T2) emerges as a significant upgrade over its first generation predecessor DVB-T. The DVB-T2 standard targets an increased system throughput by at least 30% over the DVB-T. This article introduces algorithms in the signal processing chain to improve the mobile operation for DVB-T2. The proposed modified synchronization blocks, along with the improved channel estimation, show significant improvement compared to the results reported … Show more

“…For the conventional TDS-OFDM scheme, the iterative interference cancellation with the number of maximum iterations equal to three is carried out to perform channel estimation [12], while the second received PN sequence is directly used for channel estimation in the DPN-OFDM scheme [16]. For the CP-OFDM scheme as specified by DVB-T2 [3], the pilots are used to acquire the channel frequency response (CFR) at the corresponding subcarriers, and then the robust Wiener filtering [27] with low complexity but satisfying performance is used to obtain the CFR over the whole signal bandwidth. It is clear that the MSE performance of the proposed scheme enjoys a significant SNR gain of about 7 dB compared to those of CP-OFDM and DPN-OFDM, when the channel length is close to the GI length.…”
