摘要: A technique which enables the use of a low cost non-linear power amplifier to generate wideband composite signal, such as in cellular mobile telephones (CMTs), personal communication systems (PCSs), and other multi-channel wireless system. constant envelope signal is generated from comprised combination many narrowband modulated signals. The involves adding one or more out-of-band artifact signals that accurately offset amplitude variations signal. then fed high amplifier, and, prior radio transmission amplified filtered remove As result, only desired having any required provided antenna, while at same time, through amplifier.
