H04L27/2692 - CPC Classification

Classification description:

Modulated-carrier systems; Systems using multi-frequency codes; Multicarrier modulation systems; Arrangements specific to the receiver only; Synchronisation arrangements; Link with other circuits, i.e. special connections between synchronisation arrangements and other circuits for achieving synchronisation with preamble design, i.e. with negotiation of the synchronisation sequence with transmitter or sequence linked to the algorithm used at the receiver
