Abstract

In this paper, we propose an improved preamble scheme utilizing a novel hybrid differential modulation, which can provide both the spatial multiplexing and the transmit diversity gain. The proposed preamble scheme has demonstrated a significantly improved signaling error rate (SER) performance in various channel conditions as compared to the conventional P1 symbol scheme in DVB-T2 standard. Specifically, as much as 4dB SNR gains are observed in static TU-6 and DVB-NGH outdoor channels with and without 20 Hz Doppler shift presented, respectively.
