摘要：
An adaptive MAP channel decoding apparatus and method in a mobile communication system. In the adaptive MAP channel decoding apparatus, a channel estimator calculates channel noise power and a scaling factor, a controller determines an operation mode by checking accumulated channel noise power and the scaling factor, and a MAP channel decoder performs a MAP decoding operation with an E function including a log function in a static channel mode and an E function free of a log function in a time-varying channel mode.
