Abstract: PURPOSE: A parity check apparatus for the output data of a channel card in a CDMA base station is provided to reduce the number of logics overall by directly checking parity error status without the necessity of converting a doubly demultiplexed serial data stream, outputted from a channel card of a CDMA base station and having odd parity bits, into a parallel data stream. CONSTITUTION: A data latch part(10) first latches and then outputs an even serial data stream and an odd serial data stream outputted from a CSM(Cell Site Modem) in a channel card according to a system clock of a timing and control part(40). An XOR gate(20) carries out exclusive XOR operation for the even and odd serial data streams of the data latch part(10) and the output of an AND gate(30). The AND gate(30) carries out AND operation for the output of the XOR gate(20) and a start signal of the timing and control part(40) and outputs its result as the input of the XOR gate(20). The timing and control part(40), judging the start point and end point of a word outputted from the CSM by executing an octal down count operation, outputs the start signal and an enable signal. A parity error output part(50), after latching the output of the XOR gate(20) according to the system clock of the timing and control part(40), outputs it as a parity error check result for the output data of the CSM according to the enable signal of the timing and control part(40).

Abstract: PURPOSE: A method for preventing the loss of real-time traffic data in an ATM exchange is provided to effectively utilize the traffic capacity of a port by disposing of a non-real-time service only in case that the traffic of a real-time service reaches the maximum traffic of a relevant port. CONSTITUTION: If a traffic congestion state is generated at a specific output port among the plural output communication ports of an ATM exchange switch part(S110), the congestion state is reported to the CPU of an ATM exchange(S120). The CPU gradually diminishes the bandwidth or transfer rate of a non-real-time service connected to the output port(S130). Monitoring the output port, the CPU judges whether the output port has got out of the traffic congestion state(S140). If it is judged that the output port has got out of the traffic congestion state, the CPU gradually recovers the diminished bandwidth or transfer rate of the non-real-time service(S150). Then the CPU judges whether the output port keeps a normal state(S160).

Abstract: PURPOSE: A synchronization method of a forward error correction(FEC) decoder in a mobile communication system is provided to synchronize a forward error correction decoder by efficiently searching a synchronization time point according to the FEC decoding in an MC0CDMA mobile communication system. CONSTITUTION: An FFT operation related to an FFT is performed in a physical layer for a MC-CDMA data demodulation, and at this time, generally, a starting point of the FFT is detected through an FFT frame synchronization. A receiving FEC decoder is synchronized on the basis of a starting point of the FFT frame. In the case of a symbol deinterleaver corresponding to the first module of the receiving FEC, the starting point of the synchronization detection is the same as the length of "Span*Depth" and the length of the FFT module, so that the synchronization of the symbol deinterleaver can be easily performed on the basis of the FFT starting point. Secondly, in the case of the Viterbi, a Viterbi decoder is performed on the basis of the FFT starting point. Thirdly, in the case of a synchronization of the byte deinterleaver, the synchronization can be performed on the basis of the FFT starting point. In the case of RS decoder, the point where the length of each interval in which each RS synchronization is detected maintains the frame length of the RS decoder is estimated as a synchronization of the RS decoder.
