摘要： In a method of estimating a signal-to-interference ratio (SIR), a first average channel power per slot of a first channel that is under a fading environment is estimated. A second average channel power per slot of a second channel that is under a fading environment substantially the same as the first channel is estimated, wherein the first and second channels are multiplexed. A second signal power attenuation ratio of the second channel is calculated using the second average power per slot of the second channel. A third average power per slot of the first channel is calculated using the first average power per slot of the first channel and a reciprocal of the second signal power attenuation ratio of the second channel.

摘要： A hybrid navigation system including a neural network is provided. The hybrid navigation system includes a global positioning system (GPS) as a main system using satellites and a radio determination system when there are difficulties in reception of signals from the satellites. The hybrid navigation system comprises a GPS signal processor, a TDOA signal processor and a neural network. The GPS signal processor receives GPS signals from the satellites to determine positions. The TDOA signal processor receives determination signals from mobile communication stations to determine positions. The neural network uses position values inputted from each of the GPS signal processor and the TDOA signal processor to learn and predict the position of the mobile terminal.
