“…That is, using a design based on DPSK constellation the statistics of the channel do not need to be known. Furthermore, in [16] a gain with respect to other works that also consider Rician channel was shown both for different numbers of required antennas and spectral efficiency.…”

“…Our previous designs [11] achieved a good performance with a reasonable number of antennas required in Rayleigh fading. When we have Rician channel, our designs remain valid in single user systems [16], but they are not applicable when we have a multi-user system due to the new IUI terms introduced by the LOS component, as we will show next.…”

“…In [7], some performance results for a single-user system were shown for Rician channels. The constellation was built depending on the statistics of the channel, while in our DPSK aided design [11] the constellation is fixed and independent of the statistics of the channel as we showed in [16] for the same channel conditions as in [7]. That is, using a design based on DPSK constellation the statistics of the channel do not need to be known.…”

In this paper we propose a new constellation design for a non-coherent massive single input multiple output (m-SIMO) uplink system based on M-DPSK suitable for Rician channels. Under Rician propagation, the non-coherent systems proposed until now cannot completely remove the interference. This new design takes into account the inter user and inter symbol interferences in order to convert them into useful terms which help us in the non-coherent detection. We propose an algorithm to non coherently detect the joint symbol with the information from all users leveraging the characteristics of the new constellation. In addition, the signal to interference plus noise ratio is derived and is used to present analytical bounds for the symbol error rate. It is shown that the analytical results tightly match the numerical simulation. We show that with the proposed constellation and detection algorithm we are able to leverage the LOS component of the Rician propagation, obtaining a better performance than with Rayleigh channels.

“…Tactical scenarios requiring a rapid response to threats, including a NP in the tactical radio help improve situational awareness. In addition to the emerging technologies mentioned above, it should also be noted that advances in massive MIMO are making possible the incorporation of Non-Coherent communications [9], [10], [12], [13]. This type of communication is based on the ability to demodulate signals without the need for channel estimation.…”

The proliferation of new technologies with 5G and future 6G networks may also find application in the field of military communications. However, new challenges must be considered due to the level of security required in tactical environments. In this article, we have focused on analyzing these challenges in practical use cases for military communications. First, we select and present a set of emerging technologies associated with 5G and 6G, such as Artificial Intelligence, network virtualization and softwarisation, Neuromorphic Processors, Internet of Things (IoT), Network Slicing, Tactile Internet or Blockchain, focusing on their applicability in tactical environments. On the other hand, we present an overview of the primary tactical radios that can face the challenges imposed by these technologies. Then, we show the main benefits and possible scenarios to improve efficiency in the military environment, such as situational awareness to increase the safety of soldiers on the battlefield, thanks to emerging technologies selected as potential candidates.

“…Most research has been focused on the constellation design to multiplex and non coherently detect several users. The designs based on Differential Phase Shift Keying (DPSK) [2], [3] have shown a better performance against the ones based on energy detection [4], [5]. Channel coding schemes are introduced in both designs to reduce the number of antennas for practical systems.…”
