摘要: The present invention relates to a transmission method and apparatus for transmitting signals on the basis of OFDM/TDMA-system, wherein plurality subcarriers being orthogonal each other are allocated variable number channels, channel containing depending information be transmitted in said signals, wherein, GSM-system having constant predetermined GSM-frequency channels GSM-timeslots grouped GSM-frames, is corresponding bandwidth so that multiple one resulting OFDM/TDMA-timeslot matches with or GSM-timeslots, pilot symbol every n-th subcarrier GSM-frequency-channels, whereby n an integer and>1, transmitted. also proposes receiving signals. Thereby, reliable estimate equalization can performed.
