This chapter is devoted to solving the problem of algorithms and structures investigations for Radio
Receiver Devices (RRD) with the aim of the nonlinear filtering of Digital Half-Tone Images (DHTI)
representing the discrete-time and discrete-value random Markovian process with a number of states
greater than two. At that, it is assumed that each value of the DHTI element is represented by the binary
g-bit number, whose bits are transmitted via digital communication links in the presence of Additive
White Gaussian Noise (AWGN). The authors present the qualitative analysis of the optimal DHTI filtering
algorithm. The noise immunity of the optimal radio receiver device for the DHTI filtering with varying
quantization and dimension levels is investigated
