Path detection device and path detection method

A reception apparatus provided with a path detection apparatus, said path detection apparatus comprising:

• a peak detection section that detects a peak value of a delay profile created by a received signal sampled with a predetermined sampling number chip by chip;
• a comparison section that compares power values between adjacent samples of said delay profile;
• and
• a path selection section that selects, when the power value compared by said comparison section increases or decreases consecutively up to the kth (k is a natural number of 2 or greater) forward or backward from the sample having said peak value, said kth sample as a path.

A demodulation apparatus provided with a path detection apparatus, said path detection apparatus comprising:

• a peak detection section that detects a peak value of a delay profile created by a received signal sampled with a predetermined sampling number chip by chip;
• a comparison section that compares power values between adjacent samples of said delay profile;
• and
• a path selection section that selects, when the power value compared by said comparison section increases or decreases consecutively up to the kth (k is a natural number of 2 or greater) sample forward or backward from the sample having said peak value, said kth sample as a path.

A path detection method comprising:

• a step of detecting a peak value of a delay profile created by a received signal sampled with a predetermined sampling number chip by chip;
• a comparison step of comparing power values of adjacent samples of said delay profile;
• and
• a path selection step of selecting, when the compared power value increases or decreases consecutively up to the kth (k is a natural number of 2 or greater) sample forward or backward from the sample having said peak value, said kth sample as a path.
