“…low order constellations and high code rates (CR) [14]. However, RCs may become especially effective when using multi-RF techniques, such as Channel Bonding (CB) [16], providing very high performance gains. CB has been adopted in ATSC 3.0 and consists of splitting service data across two RF channels, so that peak data rate can be doubled.…”

“…Regions 1 (Europe and Africa) and 3 (Asia) allocated the 800 MHz band (790-862 MHz, channels [61][62][63][64][65][66][67][68][69] for fourth generation (4G) LTE services, and Region 2 (America) allocated the 700 MHz band (698-806 MHz, channels [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69]. In the WRC-12, the ITU concluded with a decision to allocate additional UHF spectrum to mobile services.…”

“…A complete study on this field can be also found in [61], which shows that, in addition to a potential capacity gain, TFS can provide very important coverage gains of around 4.5 dB for a 4 RF channels multiplex, according to field measurements. On the other hand, the use of CB in ATSC 3.0 is explained in [62]. In [63], CB is combined with LDM.…”

“…The basic mode is known as plain CB, in which reception is performed by means of two tuners. The second operation mode, known as SNR averaging, exploits increased frequency diversity by means of frequency interleaving of the service data among two RF channels, thus improving transmission robustness [62]. On the other hand, TFS distributes the data of each service across multiple RF channels by means of time slicing.…”

Non-Uniform Constellations for Next-Generation Digital Terrestrial Broadcast Systems

Nowadays, the digital terrestrial television (DTT) market is characterized by the high capacity needed for high definition TV services, and the limited spectrum available. There is a need for an efficient use of the broadcast spectrum, which requires new technologies to guarantee increased capacities. NonUniform Constellations (NUC) arise as one of the most innovative techniques to approach those requirements. These constellations have been implemented in next-generation broadcast systems such as DVB-NGH (Digital Video Broadcasting -Next Generation Handheld) or ATSC 3.0 (Advanced Television Systems Committee -Third Generation). NUCs reduce the gap between uniform Gray-labelled Quadrature Amplitude Modulation (QAM) constellations and the theoretical unconstrained Shannon limit. With these constellations, symbols are optimized in both in-phase (I) and quadrature (Q) components by means of signal geometrical shaping, considering a certain signal-to-noise ratio (SNR) and channel model.There are two types of NUC, depending on the number of real-valued dimensions considered in the optimization process, i.e. one-dimensional and two dimensional NUCs (1D-NUC and 2D-NUC, respectively). 1D-NUCs maintain the squared shape from QAM, but relaxing the distribution between constellation symbols in a single component, with non-uniform distance between them. These constellations provide better SNR performance than QAM, without any demapping complexity increase. 2D-NUCs also relax the square shape constraint, allowing to optimize the symbol positions in both dimensions, thus achieving higher capacity gains and lower SNR requirements. However, the use of 2D-NUCs implies a higher demapping complexity, since a 2D-demapper is needed, i.e. I and Q components cannot be separated.In this dissertation, NUCs are analyzed from both transmit and receive point of views, using either single-input single-output (SISO) or multiple-input multiple-output (MIMO) antenna configurations. In SISO transmissions, 1D-NUCs and 2D-NUCs are optimized for a wide range of SNRs, several channel models and different constellation orders, using the Nelder-Mead optimization 3 ABSTRACT algorithm. The optimization of rotated 2D-NUCs is also investigated, including the rotation angle as an additional variable in the optimization. Even though the demapping complexity is not increased, the SNR gain of these constellations is not significant. The highest rotation gain is obtained for low-order constellations and high SNRs. However, with multi-RF techniques such as Channel Bonding (CB) or Time-Frequency Slicing (TFS), the SNR gain is drastically increased, since I and Q components are transmitted in different RF channels. In this thesis, multi-RF gains of NUCs with and without rotation are provided for some representative scenarios.At the receiver, two different implementation bottlenecks are explored. First, the demapping complexity of all considered constellations is analyzed. Afterwards, two complexity reduction algorithms for 2D-NUCs are proposed. Both algor...
