H04L27/2689 - 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

Sub-classes:

H04L27/2691 » {involving interference determination or cancellation } 202
H04L27/2692 » {with preamble design, i.e. with negotiation of the synchronisation sequence with transmitter or sequence linked to the algorithm used at the receiver} 469
H04L27/2695 » {with channel estimation, e.g. determination of delay spread, derivative or peak tracking } 323
