1. Capacitive coupling: Capacitive coupling refers to the transmission of signals or electromagnetic waves through the electric field between two dielectrics. When there is a capacitance between two circuits, the capacitance will transmit signals or electromagnetic waves from one circuit to another, resulting in interference.
2. Interference will reduce the detection sensitivity of the local discharge test. During the test, the interference level should be suppressed to the lowest level. Interference classThe types usually include: power supply interference, grounding system interference, electromagnetic radiation interference, discharge interference of various components of test equipment and various contact interference. These interferences and the way to enter the test loop. A. Power supply interference.
3. Active electronic interference is the use of a special interference transmitter to emit or forward some form of electromagnetic waves, which disrupts or destroys the work of the enemy's electronic equipment and systems. The transmission interference signal carrier frequency, power and modulation mode (interference style) are selected according to the type, operating frequency and technical system of the electronic equipment to be interfered with.
1. This question assesses the self-interference system. CDMA and TD-SCDMA are self-interference systems. GSM and WCDMA are interference-restricted systems, and WSN does not belong to mobile communication systems. Therefore, the option BCE is correct.
2. WCDMA is a way to divide the code into multiple addresses and network at the same frequency. The more users, the denser the base station and the more interference. There will be interference between users. So it's self-interference. It is a kind of 3G. GSM is a frequency division and time division system. In addition, the user will not interfere with the user.
3. The difference between the self-interference system and the interference restriction is whether users can be added.When the interference is limited, due to the interference of the neighboring area, the launch strategy of the base station and/or UE in this community is saturated, so that new users cannot be added. The self-interference system belongs to the self-start system, which does not affect the addition of users, and users can be added.
4. There are many sources of inter-network interference in mobile communication networks, including internal system interference and external system interference. System internal interference refers to the interference generated between the LTE current network cells. The causes include: cross-time slot interference, GPS out-of-step interference, interference caused by over-coverage and equipment failure, etc.
5. No service system and other phenomena. Generally speaking, when the mobile phone signal shield is working, it will emit a frequency to interfere with the downward signal of its base station. If the power of the shield is greater than that of the local base station signalThe power of the number, then the mobile phone will have no signal. If the power of the shield is less than the power of the local base station signal, the mobile phone will have a signal.
1. Man-made interference, according to its generation method, is divided into active interference and negative interference in radio communication confrontation. Positive interference is the transmission of an electromagnetic wave emitted or forwarded by the transmitter; negative interference is the use of interference that does not produce electromagnetic radiation to consciously change the propagation of electromagnetic waves.
2. In the mobile communication system, the intermodulation interference generated mainly includes: intermodulation caused by external effects, transmitter intermodulation, and receiver intermodulation.
3. There are many sources of inter-network interference in mobile communication networks, including internal system interference and external system interference.System internal interference refers to the interference generated between the LTE current network cells. The causes include: cross-time slot interference, GPS out-of-step interference, interference caused by over-coverage and equipment failure, etc.
