摘要:
In a CDMA reception apparatus, averaging part for averaging at least one of vector, amplitude and power of received signal of a plurality of transmit power control sections is provided. Further, propagation path variation estimator for estimating a propagation path variation of the present transmit power control section from respective transmit power control sections in the past to obtain a propagation path variation estimation value and propagation path variation correction part (multiplier) for correcting by the propagation path variation estimation value are further provided, wherein the averaging part averages at least one of vector, amplitude and power of received signal of the plurality of transmit power control sections corrected by the propagation path variation correction part (multiplier). With this configuration, the measurement accuracy is improved by measuring received signal power using a plurality of slots including past slots, resulting in more accurate transmit power control.
