APPARATUS AND METHOD FOR DETERMINING THRESHOLD VALUE OF RAKE RECEIVER

摘要

PURPOSE: An apparatus and a method for determining a threshold value of a rake receiver are provided to exclude a signal of a path having a receive signal strength not greater than a certain threshold value from symbol combination. CONSTITUTION: Demodulators(210a-210c) demodulate multiple receive signals each with different time delay through different radio paths, respectively. A symbol combiner(220) combines outputs of the demodulators(210a-210c) according to typical MRC(Maximal Ratio Combining). A threshold value determining unit(230) compares the outputs of the demodulators(210a-210c) with a reference threshold value, one of pre-set multiple threshold values, and selects one of the pre-set multiple threshold values according to the number of paths having signal strength not smaller than the reference threshold value.
