Title:
A METHOD AND RECEIVER FOR THE MULTI-PATH DETECTION IN CODE DIVISION MULTIPLE ACCESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/122152
Kind Code:
A1
Abstract:
A method for the multi-path detection in code division multiple access system
is provided, and the method includes the following step: A, initially detecting
multi-path for the sample points in the searching area, obtaining the sample
points for processing peak detection (300); B, detecting whether the current
nonzero points Pi and Pi+3 are both the partial peak (302),
if yes, detecting the partial double peak (304), if no, detecting the partial
single peak (303); C, buffering the delay and power information of nonzero sample
points that are detected peak (305); D, judging whether the peak detection is
ending (306), if ending, outputting the position and power information of multi-path
that are buffered (308); or else, making the Pi+1 and Pi+4
as new Pi and Pi+3 (307), returning step B. A receiver of code
division multiple access is also provided at the same time.
