POWER DETECTION OF INDIVIDUAL CARRIERS OF A MULTIPLE-CARRIER WIDEBAND SIGNAL |
摘要 |
An apparatus and method measures power of channels generated by a multiple-carrier transmitter that upconverts a plurality of baseband signals to a corresponding plurality of assigned carrier frequencies to generate an RF wideband signal. A measurement module's input interface receives a selected baseband signal and a corresponding assigned carrier frequency as well as the RF wideband signal. An undersampling component undersamples the RF wideband signal for a sampling interval to generate a plurality of measured aliased samples. A determination component determines a plurality of determined aliased samples based on the selected baseband signal upconverted to the corresponding assigned carrier frequency. A correlator correlates the plurality of measured aliased samples with the plurality of determined aliased samples to produce a correlation result. A transmit power component determines a transmitted power of the correlation result for a selected channel of the RF wideband signal corresponding to the selected baseband signal as upconverted.
