soft-decision discriminator
Technical term used in signal processing and communications engineering. Refers to a device or algorithm that makes decisions based on soft (probabilistic) information rather than hard binary decisions.
The soft-decision discriminator outputs soft-decision bits from the received signal.
硬判定 (hard decision) makes a firm binary decision, while 軟判定 (soft decision) retains reliability information. 軟判定識別器 is a device that performs soft-decision discrimination.
Compound of 軟 (soft), 判定 (decision/judgment), and 識別器 (discriminator/identifier). A technical calque from English 'soft-decision discriminator'.
