IPC: H04L7/00
Filed: 1998-10-27
Abstract: PURPOSE: An apparatus for detecting a phase difference to restore simbol timing of OFDM method receiver is provided to amend a remaining symbol timing offset. CONSTITUTION: An apparatus for detecting a phase difference to restore symbol timing ofOFDM method receiver includes a four square multiply(21), a sliding integrating apparatus(22), a delaying apparatus(23), a complex conjugate calculator(24), a complex multiply(25), a mean value measuring apparatus(26), a phase calculator(27), and a scaler(28). The four square multiply multiplies four times by a sample. The integrating apparatus extracts a mean value of them after integrating a signal from the four square apparatus with a sliding and taking a windowing as a predetermined sample. The delaying apparatus delays a signal gained from the sliding integrating apparatus. The complex conjugate calculator calculates a complex conjugate of the delayed signal. The complex multiply multiplies the complex conjugate to the mean value. The mean value measuring apparatus calculates a vector for a phase rotation difference. The phase calculator calculates a phase value for the vector and outputs the result value as a following value of a remaining symbol timing offset. The scaler scales the phase value as a predetermined unit and provides a loop filter.

CONSTITUTION: If a diagnosis begins, states of all mounted signal processing processors and signal terminals are checked. A signal terminal number and EVEN-signal processor and ODD-signal processor numbers of a group in which the signal terminals are included are recorded in a test table. A test timer is driven. A EVEN_signal processor transmits a test message to all the signal terminals, and confirms a response transmitted from each terminal. A terminal signal having the response is normally updated. A terminal signal having no response is abnormally undated. The test timer is re-drived. An ODD_signal processor transmits the test message to all the signal terminals, and confirms a response transmitted from each signal terminal. The EVEN/ODD_signal processor counts abnormal numbers. If the abnormal numbers is '0', the diagnosis is finished.
