A measurement-based methodology for the DVB-T2 MISO/SISO gain characterization in experimental networks

A Bibliographic review of wideband DTV networks using transmission diversity techniques

“…Afterwards the measurement was repeated, but this time the TV signal from the master (TX1) and slave (TX2) transmitter was broadcasted through a Rayleigh channel with twenty independent paths (TS 102 831 V1.2.1, 2012), ( Fisher, 2010) and the reference Gaussian channel, respectively. Being perhaps the most important result, the well-known negative impact of the Rayleigh channel (Morgade, 2013), (Morgade, 2014) on the broadcasted HDTV services turned out to be highly attenuated since there was only a small increase of BER ratios in the channel when compared with AWGN reference scenario. In MISO mode the same experiments were repeated using a Ricean channel (Guerra, 2012) and the obtained results were comparable with results obtained with the Rayleigh channel.…”

Channel Characteristics for Fixed and Portable DTV Reception in a Single Frequency Network

“…The flexibility and configuration options provided by the new DVB terrestrial standard have been proposed in [8], [9]. In the same way, measurements of simulated and real channel characteristics in the digital video broadcasting-terrestrial (DVB-T2) system were presented in [10], [11]. Compared with the SISO mode presented in [1], where significant destructive spectral interference is translated to higher bit error rate (BER) values, in these two works the DVB-T2 advanced multiple-input singleoutput (MISO) transmission technique has been shown to be a primary contributing factor associated with the actual digital television (DTV) platforms that fulfill modern technical requirements, and which meet user and market demands for HDTV services.…”

“…Considering the maximum values of RDS measured with a -30-dB threshold, as shown in Table III, and the ISDB-T specifications given in μs), in mode 2 with a guard interval of 1/32 (Tg = 15.75 μs), and in mode 3 with a guard interval of 1/32 (Tg = 31.5 μs), thus maximizing the spectral efficiency of the system [8]- [11].…”
