“…Opposite to the standard AWGN model, impulsive noise 3 is a non-stationary signal and may represent the main disturbing signal, such is the case of Power Line Communications Systems (PLC) [35]. This undesirable signal is also reported on Digital Television [36], audio broadcasting [37], xDSL technologies [38] as well as Underwater Acoustic systems [39]. In the frequency range from some hundreds of kHz up to 20MHz, the measurement of impulsive noise shows that it exhibits a duration of some microseconds up to a few milliseconds [40], and it could be as high as 40 dB above the background noise [41].…”

In contemporary digital communications design, two major challenges should be addressed: adaptability and flexibility. The system should be capable of flexible and efficient use of all available spectrums and should be adaptable to provide efficient support for the diverse set of service characteristics. These needs imply the necessity of limit-achieving and flexible channel coding techniques, to improve system reliability. Low Density Parity Check (LDPC) codes fit such requirements well, since they are capacity-achieving. Moreover, through puncturing, allowing the adaption of the coding rate to different channel conditions with a single encoder/decoder pair, adaptability and flexibility can be obtained at a low computational cost. In this paper, the design of rate-compatible puncturing patterns for LDPCs is addressed. We use a previously defined formal analysis of a class of punctured LDPC codes through their equivalent parity check matrices. We address a new design criterion for the puncturing patterns using a simplified analysis of the decoding belief propagation algorithm, i.e., considering a Gaussian approximation for message densities under density evolution, and a simple algorithmic method, recently defined by the Authors, to estimate the threshold for regular and irregular LDPC codes on memoryless binaryinput continuous-output Additive White Gaussian Noise (AWGN) channels.

“…[20]. Table V lists the system parameters and CNR requirements of both systems from tests in [21] and [22]. The tests show that with similar CNR it is possible to transmit UHDTV using ATSC 3.0 due to technologies applied in the system, while in ISDB-T B using all the segments it is possible to carry an HDTV signal.…”

Abstract-This review discusses the ISDB-TB and ATSC 3.0 systems, comparing the differences between the Input Formatting, passing by video compression, data multiplexing and encapsulation, the Channel coding, Interleavers, Constellation Mappers, Multiplexing methods, Framing, Waveform generation and synchronism. Finally, a performance comparison, using similar parameters, between bitrate and required Carrier-to-Noise ratio is presented. Index Terms-Digital

“…The assembling of TS was done through the free software FFMPEG [4], which allows an H.264 video encoding and AAC audio encoding, requisites for ISDB-Tb standard [3]. In addition, a multiplexing of the audio and video signals was done by setting up a TS file in the MPEG-2 standard.…”

“…Since devices that are able to assemble TS files are expensive Software implementation has become a low cost alternative which also allows laboratory testing beforehand. As proposed in [3], it is possible through the free software FFMPEG [4] coding files, which can be used for this purpose. In this work, it was proposed a way with few configurations of assembling TS to transmit the desired video to a TV.…”

Abstract-This work presents a technique for assembling a TS (Transport Stream) file, in accordance with the ISDB-Tb (Integrated Services Digital Broadcasting Terrestrial Brazilian) standard, in order to transmit it through a digital TV signal generator to analyze the parameters variation effects of the ISDB-Tb system in the BER (Bit Error Rate) performance. For this analysis, measurements were taken in three different communication channels, with distinct features. In each channel, the 16QAM and 64QAM modulations were evaluated, and several combinations were tested among the following parameters: operating mode, code rate, guard interval and time interleaving. Also, BER measurements were taken for a C/N (Carrier to Noise) range, set from transmitter, then the Eb/No ratio was calculated, which allowed to plot curves for each measure.
