Modifications of the OFDM multiple access technique improving parameters of the mobile communication, are proposed. They aim to neutralize three main drawbacks of the OFDM technique:

- Difficulties in achieving good parameters in the mobile communication using OFDMA system due to multipath propagation and the Doppler shift influence.
- Difficulty or impossibility to make soft handover.
- Big value of the peak-factor. This task can be achieved with the help of FBS and MT-FBS methods.
