  • Publication number: 20090232108
    Abstract: A method and apparatus perform I/Q imbalance estimation and compensation using synchronization signals in LTE systems. Primary and secondary synchronization signals (P-SCH and S-SCH), which carry synchronization information, are embedded in each LTE frame, and are used for receiver I/Q imbalance estimation. Additionally, the performance may be significantly improved by optimally selecting the training data in I/Q imbalance estimation.

  • Publication number: 20080141358
    Abstract: An identification and administration system applied to P2P gateway and a method for the same are proposed. The system is installed in a kernel space, and a plug-in kernel module is in the kernel space to finish preprocessing and application processing of packets on the kernel space without the need of copying data to the user space for processing. Moreover, a connection cache is provided in the kernel space to process source/destination IP addresses, connection ports and protocol identifiers of all packets to recognize and then block identical request packets in reconnections. Therefore, the throughput of content-level security gateway can be increased, and the processing efficiency of packets can also be enhanced.

  • Publication number: 20070108137
    Abstract: A heavy metal recovery system at least includes a slurry preparation unit, a reaction unit, and a pressure filtering unit. In the slurry preparation unit, a heavy metal-containing sludge cake and/or an undiluted heavy metal sludge/slurry is mixed with an acidic etching waste liquid and/or water to form slurry. The reaction unit connects to the slurry preparation metal-containing unit for the reaction that generates a heavy metal-containing reaction product. The pressure filtering unit connects to the reaction unit, and the heavy metal-containing reaction product is pressure filtered to obtain a heavy metal-containing material.
