Title: Erasure detection method for Channel Quality Indicator Channel
Inventor: KIM GI JUN
IPC: H04B7/26
Filed: 2002-12-17
Abstract: PURPOSE: A method for detecting an erasure of a CQICH(Channel Quality Indicator Channel) is provided to define a threshold value for maintaining receiving quality of a CQICH, and to determine whether to obtain or abandon data, thereby receiving with high performance as reducing data loss. CONSTITUTION: A system receives a signal of a CQICH(S11), and restores a phase of the received signal through a channel estimation value(S12,S13). The system obtains correlation values of restored receiving symbols. The system determines detection values by the correlation values(S15). The system compares one of the two detection values with a threshold value(S16). If the detection values are bigger or equal to the threshold value, the system restores the CQICH signal(S18). If the detection values are smaller than the threshold value, the system erases CQICH data.
