Abstract
The invention concerns a method of controlling the minimal distance between successive errors in digital radio transmissions when multilevel modulations are used. With such a method the errors are spaced according to the needs, with an extremely reduced use of hardware with respect to prior art techniques. The method is characterized in that, in transmission a differential delay, i.e. different from flow to flow, is applied to each parallel flow not yet modulated, and in reception a differential delay is applied to each demodulated flow in such a way that the overall delay applied to each flow, i.e. the sum of the delay applied in transmission and the delay applied in reception, is constant and equal for all the flows.
