    Abstract: A signal amplification system involves transforming at least one signal to be amplified into at least one transformed signal which is amplified and the resulting amplified transformed signal(s) can be used to produce a version(s) of the at least one original signal. The at least one transformed signal can be produced from the at least one original signal by using the at least one original signal to amplitude and/or angle (phase or frequency) modulate the at least one original signal. After amplification of the at least one transformed signal, the resulting at least one amplified transformed signal is de-modulated to produce a version(s) of the at least one signal. In transforming the at least one original signal to produce the at least one transformed signal, the at least one original signal is transformed into a more desirable form, such as a more power efficient form, for amplification. By amplifying the at least one transformed signal, more efficient and/or less costly amplifier(s) can be used to amplify the at least one signal in a linear fashion. Depending on the embodiment, at least one signal to be amplified can be transformed into at least one transformed signal by combining offset versions of the at least one original signal to produce the at least one transformed signal having the energy of the at least one signal spread in time and/or to produce the at least one transformed signal having a reduced peak to average power ratio(s)(PAR). Multiple signals to be amplified can be transformed into at least one transformed signal by combining the multiple signals, for example to produce the at least one transformed signal having a reduced peak to average power ratio(s) (PARs). After the at least one transformed signal is amplified, the resulting signal(s) can be de-modulated, inversely transformed, de-spread or reconstructed to recover a version(s) of the original signal(s).
