Get INTERFERENCE CANCELLATION - Dtic

Interference cancellation, where the adaptive filter is used to suppress an unknown interference contained (alongside an information-bearing signal of interest) in a primary signal that serves as the desired response.

10.9. The operation of an SIC receiver can be described as follows. The receiver first detects the signal sent by the first layer and after successful detection, it cancels the interference contributed by the detected signal before it detects the other layers. The process is repeated until all the layers are detected.

AIC is based on the idea of using adaptive filters to estimate and subtract the interference from the received signal, leaving only the desired signal. Adaptive filters are algorithms that can adjust their parameters automatically based on the input and output signals, and the optimization criteria.

Briefly, SIC is the ability of a receiver to receive two or more signals concurrently (that otherwise cause a collision in today's systems). SIC is pos- sible because the receiver may be able to decode the stronger signal, subtract it from the combined signal, and extract the weaker one from the residue.

Self-interference is the phenomena where a receiver's performance is degraded by unrelated emissions at the same or similar frequency to the desired signal. Self-interference, to the receiver, is simply a particular type of noise which degrades the received signal-to-noise ratio (SNR).

Successive Interference Cancellation (SIC) is a technique used by a receiver in a wireless data transmission that allows decoding of two or more packets that arrived simultaneously (in a regular system, more packets arriving at the same time cause a collision).
