“…Several identification methods based on binary or roughly quantized observations can be found in the literature [5], [6], [7], [8], [1], [9], [10], [11], [12], [13], [14]. For example, Wigren [5], [6] has developed a least-mean-square (LMS) approach to the problem of online parameter estimation from quantized observations, based on an approximation of the quantizer.…”
