Abstract
An apparatus and a method are provided for improving reception reliability for control channels by detecting time division multiple (TDM) frames transmitted through the control channels in a TDM mobile communication system. The apparatus and method include receiving the frame through the forward control channel and performing a cyclic redundancy checking (CRC) with respect to the frame, thereby outputting a first error detection bit, measuring reception power for the frame, calculating a first path metric when decoding a channel of the frame, estimating a second path metric by using the first path metric and the reception power, and outputting a second error detection bit by comparing the second path metric with a predetermined threshold value, and creating and outputting a frame quality bit for detecting validity of the frame based on the first and second error detection bits.
