Tactical communication systems based on civil standards: Modeling in the MiXiM framework

In this paper, new work is presented belonging to an ongoing study, which evaluates civil communication standards as potential candidates for the future military Wide Band Waveforms (WBWFs). After an evaluation process of possible candidates presented in [2], the selection process in [1] showed that the IEEE 802.11n OFDM could be a possible military WBWF candidate, but it should be further investigated first in order to enhance or even replace critical modules. According to this, some critical modules of the physical layer has been further analyzed in [3] regarding the susceptibility of the OFDM signal under jammer influences. However, the critical modules of the MAC layer (e.g., probabilistic medium access CSMA/CA) have not been analysed. In fact, it was only suggested in [2] to replace this medium access by the better suited Unified Slot Allocation Protocol - Multiple Access (USAP-MA) [4]. In this regard, the present contribution describes the design paradigms of the new MAC layer and explains how the proposed WBWF candidate has been modelled within the MiXiM Framework of the OMNeT++ simulator.Comment: Published in: A.

Bit-interleaved polar coded modulation with iterative decoding

Polar Codes are a recently proposed class of linear block error correction codes. They are provably capacity achieving codes over Binary Discrete Memoryless Channels (B-DMC) and have hence garnered a lot of interest from the scientific community. It is also a proposed channel coding method for 5G technology. Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) is a well known design to improve the error correcting performance of underlying channel codes over continuous channels especially Additive White Gaussian Noise (AWGN) channels. The novel idea in this paper, is to combine these powerful error correcting techniques i.e. integrate Polar Codes in a BICM-ID design to produce a high performance Bit-Interleaved Polar Coded Modulation with Iterative Decoding (BIPCM-ID) system. The error correcting performance of such a BIPCM-ID system has been analyzed through simulations over AWGN channel and multiple modulation schemes. Additionally error floor removal has been implemented and system performance has been discussed

Full-Duplex Radio - Increasing the Spectral Efficiency for Military Applications

This paper summarizes the results of the NATO STO IST Panel's Exploratory Team IST-ET-101. The team studied the full-duplex radio technology as an innovative solution to deal with the scarce and congested electromagnetic frequency spectrum, especially in the VHF and UHF bands. This scarcity is in strong contrast to the growing bandwidth requirements generally and particularly in the military domain. The success of future NATO operations relies more than ever on new real-time services going hand in hand with increased data throughputs as well as with robustness against and compatibility with electronic warfare. Therefore, future tactical communication and electronic warfare technologies must aim at exploiting the spectral resources to the maximum while at the same time providing NATO with an advantage in the tactical environment.acceptedVersionPeer reviewe
