METHOD AND SYSTEM FOR DESYNCHRONIZING CHANNELS IN MULTI-CARRIER COMMUNICATION SYSTEMS

The method involves transmitting data in a form of a frame comprising an initial synchronization preamble (12). A number of desynchronization symbols (11) are introduced at start of the frame, where the number is chosen as a function of a transmission channel number. The desynchronization symbols are adapted to introduce an offset between different channels of a multi-carrier wave form. The introduced desynchronization symbols are different for the channels. The number of desynchronization symbols equal to zero is introduced before initial synchronization preamble of the frame. An independent claim is also included for a system for reducing a peak factor in a multi-carrier high frequency (HF) communication system.
