System and method for producing amplified signal(s) or version(s) thereof

A method of producing at least one signal, said method comprising:

• splitting the signal to be amplified to produce first and second versions;
• delaying the second version within a delay circuit to produce a time-delayed version of the first version;
• combining the first version and time-delayed version within a combiner to produce at least one transformed signal having a reduced peak-to-average ratio;
• and
• amplifying said at least one transformed signal to be later inversely transformed.

A method of producing a signal, said method comprising:

• splitting the signal to be amplified to produce first and second versions;
• delaying the second version within a delay circuit to produce a time-delayed version of the first version;
• combining the first version and time-delayed version within a combiner to produce at least one transformed signal having a reduced peak-to-average ratio;
• amplifying said at least one transformed signal into at least one amplified transformed signal;
• and
• constructing at least one amplified signal from said at least one amplified transformed signal by inverse transformation.

A method of producing versions of a signal, said method comprising:

• transforming a signal to be amplified into transformed signals by splitting the signal to be amplified to produce first and second versions;
• delaying the second version within a delay circuit to produce a time-delayed version of the first version;
• combining the first version and time-delayed version within a combiner to produce a first transformed signal and second transformed signal having reduced peak-to-average power ratios;
• amplifying said transformed signals into amplified transformed signals;
• and
• processing said amplified transformed signals to produce versions of said signal having a relative delay for transmission on separate antennas.

A method of producing signals on separate antennas, said method comprising:

• transforming at least one signal to be amplified into transformed signals by splitting the signal to be amplified to produce first and second versions;
• delaying the second version within a delay circuit to produce a time-delayed version of the first version;
• combining the first version and time-delayed version within a combiner to produce a first transformed signal and second transformed signal having reduced peak-to-average power ratios;
• amplifying said transformed signals into amplified transformed signals;
• and
• providing said amplified transformed signals for transmission so said amplified transformed signals or processed versions thereof are transmitted on separate antennas.

An apparatus for producing a signal comprising:

• a splitter for receiving a signal and splitting the signal into first and second versions on first and second paths;
• a delay circuit positioned on the second path for delaying the second version to produce a delayed in time version;
• a combiner for receiving the first version and second delayed in time version and producing at least one transformed signal having a reduced peak-to-average power ratio;
• and
• an amplifier circuit for receiving and amplifying the at least one transformed signal to be later inversely transformed.
