Channel probing with STANAG 4285 waveform for ACS within a net

The article provides guidelines to build a consistent definition of an automatic radio control system (ARCS). Automatic channel selection (ACS) is introduced as a central piece for HF adaptivity: it is a background task for intelligent automatic link establishment (ALE) and automatic link maintenance (ALM) (i.e. joint selection of suitable channel and traffic parameters for a link within a network). ACS is a decentralized process which consists in two parts: an (automatic channel probe) ACP between participating units (PUs) to estimate physical channel parameters and a matching process with reference databases in each PU between previous channel parameters and a user service request. An ACP signal processing HR algorithm with STANAG 4285 waveform has been stressed to produce relevant CIR and SNR accuracy to a further matching process for above 0 dB mean SNR multipath channels. ACP may then be a key component in handling sensitive high data rate traffic waveforms when the probing power is comparable or at least not much below normal traffic transmission power. The design of network configurations for both meshnets and N-starnets have stressed that an inaccurate knowledge of the remote SNR may lead to a reduced matching process ability unless the process is reinforced with data processing features as well as a system design such as channel history maintenance and a hand-shaking ALE
