Abstract
The assessment of a signal/noise ratio and (or) noise parameters is necessary for effective functioning of most of soft-decision decoding, capacity control and resource allocation algorithms realized in telecommunication systems. Such items are of vital importance for pulse noise jamming channels when a signal-to-noise ratio is variable, i.e. impulses (symbols, elements of a signal-code construction) are accepted in the conditions of a changing parameters noise.
The assessment of a signal/noise ratio and (or) noise parameters is usually formed as a result of processing consecutive timing cycles of a signal noisy mixture, concurrently special measurement channels may be employed. In multichannel devices of orthogonal signals required input information (observation) may be measured at the time of channel outputs and a signal/noise ratio and (or) noise parameters may be assessed without using special measurement channels.
