Method and circuit layout for the transmission of messages by means of approximating hermitian functions

摘要

A method and circuit arrangement for transmission of messages in which a number of L components (m₀, . . . , m_L-1) are coded by means of orthogonal functions to a signal (s(t)), and in which approximations of hermitic functions are used as orthogonal functions. A Fourier transform is performed on the received signal and subsequently decoded with the aid of the orthogonal functions.
