Method and apparatus for frequency conversion, in particular for controlling the emitting power of a cellular mobile telephone

摘要

The process involves modulating an incident signal to generate a binary signal (SCB) representing the signal, and generating a periodical auxiliary signal (SAX) with frequency equal to a desired transposition frequency. The signal (SAX) is followed through inversions and non-inversions to generate a transposed signal (STR). An amplitude of the auxiliary signal is adjusted based on a desired power for the signal (STR). - An INDEPENDENT CLAIM is also included for a wireless communication system component including a frequency transposition device.
