Patent ID: 7245681

Claim:
A receiving terminal for a CDMA system, comprising: a plurality of finger circuit elements, each of said plurality of finger circuit elements for making a correlation between a received signal from a radio circuit connected to an antenna and a known signal and for outputting a correlated received signal as a result of the correlation; and a rake circuit for combining the correlated received signals output from the plurality of finger circuit elements to provide a synthesized received signal; wherein the rake circuit is configured to execute electric field level judgment based on the correlated received signals output from the plurality of finger circuit elements and a predetermined threshold level; wherein the rake circuit is configured to obtain a difference between (i) a particular electric field level of a particular correlated received signal output from a particular finger circuit element of the plurality of finger circuit elements and (ii) a certain electric field level of a certain correlated received signal output from a certain finger circuit element of the plurality of finger circuit elements, and is configured to compare the difference with the predetermined threshold level as part of the electric field level judgment; and wherein an operation of at least one finger circuit element of the plurality of finger circuit elements can be suspended for a fixed, predetermined time period according to a result of the electric field level judgment.
