Abstract:
1. A CDMA reception apparatus comprising: a received signal power measurement part comprising: propagation path variation estimation means for estimating propagation path variations between respective prior slots and a current slot to obtain propagation path variation estimation values, wherein each of the propagation path variation estimation values is obtained by dividing an amplitude of a signal received at the current slot by an amplitude of a signal received at a different corresponding prior slot; propagation path variation correction means for generating a first plurality of corrected products, each corrected product obtained by multiplying at least one of vector, amplitude, or power of a received signal of the different corresponding prior slot by said propagation path variation estimation value obtained by dividing the amplitude of the signal received at the current slot by the amplitude of the signal received at the corresponding prior slot; and averaging means for averaging the first plurality of corrected products.
