Definitions

  • the preferred embodiments of the invention are disclosed in the dependent claims.
  • the method and arrangement of the invention provide many advantages.
  • the method of the invention enables the optimization of the transmission capacity of a frequency band with respect of propagation conditions and transmission needs at a given time.
  • the channel quality is bad, a smaller amount of information can be reliably transmitted.
  • the transmission capacity can be increased. Consequently, in good propagation conditions no underutilization of the channel occurs, which is the case in the existing methods.
  • Figure 1 illustrates an example of a system to which the invention can be applied
  • Figure 4 is a block diagram illustrating a third example of the structure of the transmitter of the invention.
