Abstract
Good receiving characteristics are achieved by receiving a path immediately after the path appears. A path timing comparing section compares correlation peak values and their path timings detected from a delay profile with correlation peak values and their path timings assigned to fingers in the previous cycle. If a path timing determining section determines from the comparison result that a path with high intensity level has appeared, it immediately assigns the path to a finger. This enables maintaining good receiving characteristics.
Claims30
A demodulation apparatus for mobile communication having capability of cyclically selecting signals that meet a predetermined condition out of signals incoming via different paths, combining the signals, and outputting the combined signals, comprising:
- the apparatus comprises threshold setting means;
- and
- signal selecting means for comparing an incoming signal with a threshold set by said threshold setting means and for selecting said compared signal according to said comparison result even if said signal does not meet said predetermined condition.
A demodulation method for mobile communication providing capability of cyclically selecting signals that meet a predetermined condition out of signals incoming via different paths, combining the signals, and outputting the combined signals, comprising:
- a first step of setting a threshold;
- and
- a second step of comparing an incoming signal with a threshold set by said first step and selecting said compared signal according to said comparison result even if said signal does not meet said predetermined condition.
A recording medium on which a control program for a demodulation method for mobile communication is recorded, the demodulation method providing capability of cyclically selecting signals that meet a predetermined condition out of signals incoming via different paths, combining the signals, and outputting the combined signals, wherein
- the control program is recorded on the recording medium and comprises a first step of setting a threshold, and a second step of comparing an incoming signal with a threshold set by said first step and selecting said compared signal according to said comparison result even if said signal does not meet said predetermined condition.
