WebA 25 Hz pilot tone is added to trigger receivers; unlike its counterpart in FM radio, this carrier is not necessary for the reconstruction of the original audio sources. Description [ edit ] The C-QUAM signal is composed of two distinct modulation stages: a conventional AM version and a compatible quadrature PM version. WebChannel estimation for mobile OFDM systems requires transmission of pilot tones. This paper addresses the important issue of selecting these pilot tones, so as to achieve a good quality estimate. It is shown that the best set of tones to be used are those which are equally spaced. Furthermore, it is shown using the case of a first order Markov channel, that it is …
