Estimation-correlation-compensation signal processing in the presence of interferences: A review
Yu. G. Sosulin, V. V. Kostrov · Journal of Communications Technology and Electronics · 2006
One of the directions of signal processing in the presence of interferences that involves the estimation-correlation (EC) reception technique and the interference compensation is reviewed. Optimal and quasioptimal estimation-correlation-compensation (ECC) algorithms for the detection of arbitrary signals in the presence of arbitrary interferences and noise with independent realizations are analyzed. It is demonstrated that the ECC method leads to the estimation-compensation algorithms in the case of estimating desired signals and to the compensation-correlation algorithms in the case of detecting deterministic or weak random signals. The features of the EC and ECC algorithms and the corresponding estimates are discussed for the cases of continuous and discrete observations. A comparative analysis of the structures of the optimal and quasi-optimal ECC detectors is presented. Several practical problems regarding signal processing and interference compensation that are solved via the EC and ECC reception techniques are analyzed.
