“…From the receiver side, there are also implications for the constellation design. We suggest designing the constellation as simple as possible to enable a simple demapping process in order to ensure reliability and to keep latency within acceptable limits [146], [147], [148]. We have based this recommendation on some common and simple receiver architectures, such as QPSK (formed of 2 PAM schemes) [149], or the M-ary APSK [150], which are commonly used in satellite applications.…”

The choice of modulation schemes is a fundamental building block of wireless communication systems. As a key component of physical layer design, they critically impact the expected communication capacity and wireless signal robustness. Their design is also critical for the successful rollout of wireless standards that require a compromise between performance, efficiency, latency, and hardware requirements. This paper presents a survey of constellation design strategies and associated outcomes for wireless communication systems. The survey discusses their performance and complexity to address the need for some desirable properties, including consistency, channel capacity, system performance, required demapping architecture, flexibility, and independence. Existing approaches for constellation designs are investigated using appropriate metrics and categorized based on their theoretical algorithm design. Next, their application to different communication standards is analyzed in context, aiming at distilling general guidelines applicable to the wireless building block design. Finally, the survey provides a discussion on design directions for future communication system standardization processes.INDEX TERMS Bandwidth, communication waveforms, mobile communications, spectral efficiency, wireless communications.

“…In recent years, different comparisons between theoretical and practical planning methods for DVB-T2 are presented in [17]- [20]. For instance, the authors in [17] proposed a new timing detection metric for frequency-selective fading. The symbol timing synchronization scheme was investigated to improve the estimation accuracy.…”

“…An optional initial stage, known as MISO processing in the DVB-T2 standard, provides the initial frequency domain coefficient, which is processed by a modified Alamouti [33]. Then, the DVB-T2 signal to be split between two groups of transmitters on the same frequency without the interference of signals [17].…”

This paper addresses a novel Alamouti space-frequency block decoding scheme with discontinuous Doppler diversity (DDoD) and cyclic delay diversity (CDD). We investigate different antenna diversity concepts, which can be applied to orthogonal frequency division multiplexing (OFDM) systems over highly frequency selective channels. The main object of this research is standard compatibility and the effect of simple diversity techniques on the channel fading properties. Therefore, we analyze a receiver in terms of the effective channel transfer function, which leads to the possibility of optimizing diversity. Besides, a novel transceiver using DDoD is proposed, which increases the Doppler spread of the multipath fading channel without causing additional Intercarrier Interference (ICI). Moreover, an efficient Alamouti encoder and decoder based on CDD is proposed, which allows a high reliability and capacity enhancement. In order to evaluate the capability of that, we have implemented this scheme for the second-generation terrestrial video broadcasting (DVB-T2) system over different channels. Furthermore, mathematical analysis and simulation results show the bit error performance of the modified encoding method with these diversity techniques, performs mostly better than the other forms of encoding Alamouti over highly frequency-selective channels such as single frequency networks (SFN). The other advantages of the proposed method are simplicity, flexibility, and standard compatibility.
