A decoding apparatus and method of a terminal in a wireless communication system are provided. A carrier to interference and noise ratio (CINR) estimator estimates a CINR value of a received signal, and a controller generates a modulation and coding scheme (MCS) level candidate set satisfying the estimated CINR value and a target packet error rate (PER) based on a look-up table. A decoder switch determines if an MCS level of a burst is included in the MCS level candidate set when the burst having no connection identifier (CID) information exists in a corresponding frame, and determines to decode the corresponding burst if the MCS level of the burst is included in the MCS level candidate set and to discard the burst otherwise.

An apparatus and a method for selecting an operation mode to improve a throughput in a mobile communication system are provided. The apparatus includes a Carrier to Interference and Noise Ratio (CINR) predictor for predicting a probable average and dispersion for a CINR measured using a preamble of a received pilot signal or radio signal, a metric calculator for calculating a throughput for each Modulation and Coding Scheme Level (MCS_Level) by using the probable average and dispersion for the predicted CINR and for selecting an MCS_Level having a maximum throughput, and an operation mode selector for selecting an operation mode of the selected MCS_Level having the maximum throughput.
