Title:
DEVICE AND METHOD FOR MEASURING NON-ORTHOGONAL NOISE POWER FOR CDMA COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO1999066643
Kind Code:
A3
Abstract:
A non-orthogonal noise detecting device for a CDMA communication system. In the device, a despreader (311) despreads multiple channel signals including a specific channel with an orthogonal code assigned to the specific channel repeating at least two same second symbols at a given first symbol duration, to generate despread repeated symbols. A difference signal generator (315, 317) receives the despread second symbols, and generates a difference signal between a presently received second symbol and a previously received second symbol. A noise detector (319) converts the difference signal to an energy value to generate a nonorthogonal noise signal.
