Near-end crosstalk

Japanese: 近端漏話 - きんたんろうわ

…Crosstalk is a phenomenon in which, in signal transmission using wire cables, etc., electromagnetic or electrostatic coupling between two or more cables causes the signal of one cable to leak into another cable, resulting in mutual interference. Depending on the end point at which the interfering crosstalk signal appears, it is distinguished as near-end crosstalk, far-end crosstalk, etc. In wireless communication, for various reasons, radio waves from a station other than the one you want to receive may be mixed in and receive, causing interference. …

From [Crosstalk]

…The line that causes crosstalk is called an induced line, and the line that is disturbed is called an induced line. There are two types of crosstalk: far-end crosstalk, which occurs in the same direction as the signal transmission direction of the induced line, and near-end crosstalk, which occurs in the opposite direction. Near-end crosstalk has a large impact because a large signal on the transmitting side leaks into a small signal on the receiving side, and countermeasures against near-end crosstalk are generally the challenge. …

…漏話は，ワイヤケーブルなどを用いた信号伝送において，二つ以上のケーブル間の電磁的，あるいは静電的結合により，一つのケーブルの信号が他のケーブルに漏れ，相互に干渉を起こす現象である。妨害となる漏話信号の現れる端点に対応して，近端漏話，遠端漏話などの区別がなされる。無線通信においても，種々の原因により，受信したい送信局以外の電波が混入受信され，混信を起こすことがある。…
