Hertzian multi-channel signal`s digital pre-correction method for e.g. digital audio broadcasting, involves applying correction to each signal supporting channel based on percentage between instantaneous amplitudes

摘要

The method involves calculating an instantaneous power of each signal supporting a channel and a total instantaneous power of a multi-channel signal. Percentage between instantaneous amplitude of each signal supporting the channel and total instantaneous amplitude of the multi-channel signal is calculated. The correction is applied to each signal supporting the channel based on the calculated percentage. Independent claims are also included for the following: (1) a device for digital pre-correction of hertzian multi-channel signal (2) a computer program product stored on a storage medium comprising instructions for implementing a digital pre-correction method.
