ELECTRIC POWER MEASURING APPARATUS, ELECTRIC POWER CONTROL APPARATUS, WIRELESS COMMUNICATION APPARATUS, AND ELECTRIC POWER MEASURING METHOD

摘要

A power measuring apparatus capable of accurate power measurement through segment averaging of a signal obtained by code division multiplexing a plurality of channels having different periods or timings at which their power levels change, a power control apparatus and radio communication apparatus provided with this power measuring apparatus and a power measuring method are disclosed. In this power measuring apparatus, an averaging start timing control section (105) inputs an averaging start timing signal to an averaging section (103) basedon information input from a power change timing analysis section (106) when a longest segment identified by the power change timing analysis section (106) arrives. When the averaging start timing signal is input, the averaging section (103) starts to calculate a segment mean value of the input signal.
