Title: Method for mitigating passive intermodulation and an apparatus therefor
Inventor: WANG FANGGANG
IPC: H04B1/10
Filed: 2020-02-04
Abstract: There is provided mechanisms for mitigating passive intermodulation in a first network node, wherein said PIM is caused by radio signals transmitted from at least an adjacent network node. The method is performed by a control device. The method comprises receiving at least an uplink radio signal and down-converting the received UL radio signal to a UL baseband signal. The method applies a cyclic redundancy check, CRC, to detected information bits of the received UL baseband signal, wherein in response to determining by the CRC that the UL baseband signal is detected correctly, directly output the detected information bits. The method comprises in response to determining by the CRC that the UL baseband signal is incorrectly detected, determining a residual signal of the received UL baseband signal applying a blind signal identification scheme on the residual signal of the UL baseband signal to obtain an estimate for a modeled PIM signal. The method comprises subtracting the estimated modelled PIM signal from the received UL baseband signal as in the first step and updating the received UL baseband signal in an iterative process until CRC is detected correctly or until number of iterations exceeds a predetermined threshold.

Title: Pixel circuit and drive method therefor, display substrate and display apparatus
Inventor: CHEN SHUAI
IPC: G09G3/3258
Filed: 2020-04-21
Abstract: Provided are a pixel circuit and a drive method therefor, a display substrate and a display apparatus. A light-emitting control circuit can output a direct-current power supply signal provided by a direct-current power supply end to a second node and control the conduction between a third node and a light-emitting element, and a compensation circuit can adjust the potential of a first node according to the potential of the second node. Therefore, when a pixel circuit is driven, the potential finally written into the first node is only related to a threshold voltage of a drive transistor, the potential of a data signal provided by a data signal end and the potential of the second node. Moreover, a drive signal output by a drive circuit is related to the difference between the potential of the first node and that of the second node, and therefore, the drive signal output by the drive circuit is unrelated to the potential of the second node, that is, the drive signal is unrelated to the potential of the direct-current power supply signal. Thereby, the problem of uneven display brightness of a display panel caused by a reduction in transmission due to the potential of the direct-current power supply end is prevented, and the display effect of the display panel is relatively good.
