adjacent channel

USAGE SUMMARY

The phrase "adjacent channel" is correct and usable in written English.
It is typically used in contexts related to telecommunications, audio, or broadcasting to refer to a channel that is next to another channel in frequency or position. Example: "The interference was caused by signals from an adjacent channel, which disrupted the clarity of the transmission."

§ 90.221 Adjacent channel power limits.

Cornell University

As such, regulatory based very stringent adjacent channel leakage ratio (ACLR) and adjacent channel selectivity (ACS) requirements can be met.

Physical Communication

Also, when turned to one of its extreme values, the potentiometer would kill the signal in the adjacent channel.

Cornell University

The selectivity refers to the ability of the receiver to reject adjacent channel signals.

RF Components and Circuits

The adjacent channel crosstalk ranges from −19.02 dB to −8.29 dB.

Optics Communications

An incident polarized beam will couple to an adjacent channel if it is parallel to the channel.

Optics Communications

However, in dense networks, the dynamic channel access leads to a higher probability of adjacent channel interference (ACI).

Computer Communications

The single-sideband phase noise performance of the local oscillator is important to the receiver's adjacent channel selectivity.

Expert writing Tips

Best practice

When discussing technical specifications, clearly define the frequency separation or bandwidth characteristics of the "adjacent channel" to avoid ambiguity.

Common error

Avoid using "adjacent channel" when you actually mean co-channel. An adjacent channel is next to the desired channel in frequency, whereas a co-channel uses the same frequency.

Linguistic Context

The phrase "adjacent channel" primarily functions as a descriptor, specifying a channel's position relative to another in the frequency spectrum or in a sequence. As Ludwig AI explains, it is considered correct and usable in written English. This is evident in the provided Ludwig examples where it modifies terms like 'power', 'interference', and 'selectivity'.

Ludwig's WRAP-UP

The term "adjacent channel" is a grammatically sound and widely used descriptor, primarily found in scientific and academic contexts. As Ludwig AI states, its purpose is to denote a channel's position relative to another in the frequency spectrum, a crucial aspect in fields like telecommunications and signal processing. Analysis of the Ludwig examples reveals that the term commonly appears when discussing interference, selectivity, and power ratios, highlighting its technical significance. While alternatives like "neighboring channel" exist, "adjacent channel" offers a specific technical meaning. When using this term, it's essential to avoid confusion with co-channel and to clearly define the frequency characteristics being discussed.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

neighboring channel

Emphasizes spatial proximity rather than a specific technical relationship.

contiguous channel

Highlights the unbroken sequence or connection between channels.

adjoining channel

Stresses the shared boundary between channels.

proximate channel

Focuses on the closeness of the channels, without necessarily being directly next to each other.

nearby channel

Suggests the channels are in the same general vicinity, not necessarily sequential.

successive channel

Highlights the order in which the channels follow each other.

next-door channel

More informal way to denote a channel that is immediately next to another.

flanking channel

Indicates that a channel is on either side of a given channel.

surrounding channel

Implies the channel is enclosed or encircled by other channels.

bordering channel

Highlights the channels sharing a border but does not imply direct adjacency.

FAQs

How does "adjacent channel" interference affect wireless communication?

Adjacent channel interference occurs when signals from a neighboring frequency band leak into the desired channel, degrading signal quality and potentially reducing data throughput. Mitigation techniques include proper filtering and channel allocation.

What is the difference between "adjacent channel" and co-channel interference?

Adjacent channel interference involves signals from "neighboring channel"s, while co-channel interference arises from signals using the same frequency band. They require different strategies for mitigation.

What are some metrics used to evaluate "adjacent channel" performance?

Key metrics include Adjacent Channel Leakage Ratio (ACLR), Adjacent Channel Selectivity (ACS), and Adjacent Channel Power Ratio (ACPR). These metrics quantify the amount of signal leakage into adjacent channels and the receiver's ability to reject those signals.

In what contexts is the term "adjacent channel" commonly used?

The term "adjacent channel" is frequently used in telecommunications, broadcasting, and audio engineering to describe channels that are next to each other in the frequency spectrum. It's essential for discussing interference and spectrum management.
