DEVICE AND METHOD FOR MEASURING NON-ORTHOGONAL NOISE POWER FOR CDMA COMMUNICATION SYSTEM |
摘要 |
A non-orthogonal noise detecting device for a CDMA communication system. In the device, a despreader 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 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 converts the difference signal to an energy value to generate a non-orthogonal noise signal. |
