    摘要： An apparatus for measuring Optical Beat Interference (OBI) noise is applied to a central office in a Subcarrier Multiple Access (SCMA) optical network. The central office includes an optical receiver for converting an optical signal received through an optical fiber into an electrical signal. The OBI noise measurement apparatus includes a power divider, first and second filters, and a power measurement unit. The power divider divides the power of a signal output from the optical receiver into two signals. The first filter passes one of the two signals divided by the power divider in a low band of frequencies below a band of subcarrier signals. The second filter passes the other of the two signals divided by the power divider in a high band of frequencies above the band of subcarrier signals. The power measurement unit measures the power of each signal passed through the first and second filters.

    摘要： A digital broadcasting system and a data processing method are disclosed. A receiver receives a broadcast signal including mobile service data and main service data. A known data detector detects known data from the broadcast signal. An equalizer performs channel equalization on the mobile service data received by means of the detected known data. An RS frame decoder acquires an RS frame from the channel-equalized mobile service data. A management processor extracts a Generic Stream Encapsulation (GSE) packet from a GSE Base Band (BB) constructing one row of the RS frame, and calculates an IP datagram from the extracted GSE packet. A presentation processor displays broadcast data using data contained in the calculated IP datagram.
