  • Patent number: 10965389
    Abstract: A new method of performing interference estimation to allow the data packets to be efficiently delivered in an OFDM system. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. Based on the estimated interference, the CIR can be determined by the BTS based on channel response estimates made by the BTS, or by the MS based on channel response estimates made for the uplink assuming a symmetrical channel. Numerical results show that the CIR estimation error could be very small if a sub-channel is considered as the minimum transmission unit. In terms of the aggregate throughput, the interference estimation method can provide a significant gain.

The photosensitive element and the voltage divider are connected in series between two power terminals. The gate of the detection transistor is connected to a first voltage dividing node between the photosensitive element and the voltage divider. Therefore, when the resistance of the photosensitive element becomes smaller under illumination, the voltage of the first voltage dividing node correspondingly rises, and the detection transistor is turned on and may output a current to a read line under the driving of a DC power terminal. The magnitude of the current is determined by the magnitude of the voltage of the first voltage dividing node.
