Interference
It is (countable and uncountable, plural Interference)—the mutual reference between two or more things. Interference is made up of two words inter and reference. Inter means between among in the midst. Reference means to trace something back, ‘to refer to something’) The internal reference is a certain information/sequence of numbers/internals you assign internally to find/sort/order orders. The internal reference does not appear on the invoice or other printouts.
Types of Interference
- Co-channel Interference
- Adjacent Channel Interference
1. Co-channel Interference
In frequency reuse, several cells within a given coverage area use the same set of frequencies. When 2 channels use the same set of frequencies is called Co-channel Interference. Co-channel Interference cell is called Co-channel Interference. Co-channel Interference cannot be reduced by simply increasing the transmit power. An increase in the transmit power causes Interference in the other cell. Channels cells must be separated by a certain minimum distance. Cells in clusters 1 and 2 use the same frequency mobile in cluster 2. Reverses the signal from the base station in cluster 1. It is termed a Co-channel Interference radius. The radius of the cell is to transmit power.
- Decreasing the transmit power per cell.
- Making cells smaller.
- filling vacated coverage areas.
Q=D/R
- Q = Co-channel Reuse Ratio.
- D = Distance to the center of the nearest Co-channel cell.
- R = Radius of cell.
2. Adjacent Channel Interference
When the transmission from adjacent channels interferes with each other. Adjacent Channel Interference means next. This interference occurs due to fitters in the receiver. It causes the frequencies to enter nearby channels. When an adjacent channel is transmitting very close to a mobile unit receiver and at the same time the mobile unit is trying to receive a signal from the base station on the Adjacent frequency it causes Adjacent Channel Interference. Its effect is also called a nearby effect.
Effect of Interference
The mobile unit is receiving a signal ( f1) at the same time base station transmits a signal (f2) to another mobile unit nearby causing f2 to be transmitted at a much higher power than the f1 power level. Receives f2 at a much higher power level than f1. Filter in unit I can not block all the energy from f2—the signal from unit 2 interfaces with unit 1. However, f1 does not interfere with unit 2 because it is a weak signal received.
