Method and apparatus for reducing mutual interference of multi-carrier

A method for reducing mutual interference of multi-carrier, comprising:

• adjusting a delay of at least one modulation signal;
• modulating each adjusted modulation signal onto respective modulated signal;
• and
• comparing performance indices of modulated signals with set performance indices, and adjusting the delay of at least one modulation signal according to a priority level and a step size when the set performance indices are not reached, until the performance indices of modulated signals reach the set performance indices, and setting each current modulated signal as an input signal when the set performance indices are reached,
• wherein the priority level is determined according to a number of the modulation signals' frequencies and the modulation signals' positions;
• the step size is changed dynamically according to difference between the performance indices of modulated signals and the set performance indices.
