Abstract:
A new method of generation wideband orthogonal sequences sets with liner modulation method has been proposed. It\'s shown that choosing proper target function, generation task is to be reduced to discrete optimization task. The last is solved by using the Bellman-s optimality principle and generalized Viterbi algorithm. The paper includes examples of generation wideband orthogonal signals for noncoherent and coherent reception with PM-2 and PM-4 modulation methods.
