Digital Video Broadcasting via satellite second generation has experienced worldwide adoption because of its revolutionary and yet practical physical layer technology and its flexibility. Recently, the standard has been updated with several new features without changing its fundamental structure. This paper provides a high-level discussion on several of the most important additions to the new standard with particular emphasis on some of the new signal constellations.Consequently, the 2 + 4 + 2APSK constellation can often be operated with pilots switched off, resulting in 2.5% overhead reduction. This benefit comes on top of an SNR gain of 0.2dB for standard (non-iterative) demapping and LDPC decoding. Phase noise resilienceThe DVB-S2X User Guidelines [8] detail the phase noise assumptions for the different satellite system components and for various service types, resulting in end-to-end phase noise masks denoted as P1 Figure 3. 64-Ary constellation of DVB-S2X.Figure 4.

His research interests include system synchronisation, waveform design, optimal resource scheduling, channel estimation, and distortion/interference countermeasures. He made key contributions to widely deployed standard-based and proprietary satellite transmission technologies and served on the DVB ad hoc workgroups evolving the DVB-DSNG, DVB-RCS, DVB-S2, DVB-S2X, and DVB-CID specifications. He received his Masters degree in Electrical Engineering from the

This paper introduces a low complexity method for antenna sector selection in mmWave Hybrid MIMO communication systems like the IEEE 802.11ay amendment for Wireless LANs. The method is backwards compatible to the methods already defined for the released mmWave standard IEEE 802.11ad. We introduce an extension of the 802.11ad channel model to support common Hybrid MIMO configurations. The proposed method is evaluated and compared to the theoretical limit of transmission rates found by exhaustive search. In contrast to state-of-the-art solutions, the presented method requires sparse channel information only. Numerical results show a significant complexity reduction in terms of number of necessary trainings, while approaching maximum achievable rate.
