    摘要: An apparatus and a method for handover between a broadband wireless communication system and a heterogeneous communication system are provided. An operating method of a base station for the handover between a broadband wireless communication system and a and a heterogeneous communication system includes when a terminal enters a border cell, sending a message requesting to measure a signal level of a downlink, to the terminal, when a signal level measured by the terminal falls below a preset threshold, requesting a handover, to a corresponding heterogeneous communication system, over a core network, receiving a message, including channel allocation information for the handover, from the corresponding heterogeneous communication system, and forwarding the message, including the channel allocation information, to the terminal. Hence, when the terminal gets out of the service coverage area of the broadband wireless communication system, it can be handed over to the heterogeneous communication system seamlessly.

    摘要: In a communication system, a plurality of radio access systems (RASs) respectively receives connection resources from an MBS server for transmitting a multicast broadcast data packet. The MBS server is involved in transmission of the multicast broadcast data packet. Then, the plurality of RASs receive the multicast broadcast data packet including parameters for synchronization between the plurality of RASs and parameters for size and location of the multicast broadcast data packet and deliver the received multicast broadcast data packet to a portable subscriber station (PSS). Thereby, the plurality of RASs can transmit the multicast broadcast data packets with the same location and the same size to the PSSs at the same time.

    摘要: A pattern matching method for use in manufacturing a semiconductor memory device increases a pattern matching rate between a GDS image and an SEM image. The pattern matching method includes extracting a scanning electron microscope (SEM) image and a graphic data system (GDS) image to perform a pattern matching; performing a two-dimensional furrier transform (FFT) for the extracted GDS image and analyzing a low spatial frequency; deciding whether or not a pattern is a repeated pattern or non-repeated pattern by using the analyzed low spatial frequency; and limiting an X/Y range for a pattern matching when the decision result is for the repeated pattern, and then performing the pattern matching between the SEM image and the GDS image.
