AdjacentChannelInterferenzen
AdjacentChannelInterferenzen, also known as adjacent channel interference (ACI), is a form of radio-frequency interference that occurs when energy from a transmitter leaks into a neighboring channel, degrading reception on that channel. It is most common in systems that rely on tightly spaced channels or where emissions masks are not strictly enforced.
Causes include inadequate transmitter filtering, poor receiver selectivity, and spectral leakage from high-power transmitters. Nonlinearities in
Effects vary by application but typically include reduced signal-to-noise ratio, audible distortion in audio services, data
Measurement and regulation: ACI is assessed using metrics like Adjacent Channel Leakage Ratio (ACLR) or adjacent-channel
Mitigation: Solutions include stricter spectral masking, wider guard bands, better RF filtering at transmitter and receiver,
Applications: ACI is relevant across broadcast, cellular, Wi-Fi, and other wireless services, where tight channel plans
