Abstract
The feasibility of the high speed Viterbi decoder with a circularly connected 2-dimensional analog CNN cell array has been investigated. In the previous study, the CNN-based analog Viterbi decoder was reported, in which a part of the trellis diagram of the convolutional coder is designed with analog circuit-based cells and connections. The circuits of the trellis diagram are connected circularly, forming a cylindrical shape so that the cells of the last stage are connected to those of the first stage. In this study, the performance of the CNN-based analog Viterbi decoder circuits have been measured through circuit simulations and its hardware feasibility has been investigated with two different kinds of tests such as the worst-case simulation and the Monte Carlo analysis. Results of such simulations are included.
