1. device that is used to transmit pilot tone and data comprises:

  • Processor is used to form a pilot frequency code element sequence, forms a sequence of data symbols, and with said sequence of data symbols and said pilot frequency code element sequence time division multiplexing;

    AndModulator is used for generating at least one single-carrier frequency division multiple access (SC-FDMA) code element based on said time-multiplexed data symbols and pilot frequency code element, and each in said at least one SC-FDMA code element comprises Cyclic Prefix.
