| 20120106318 | METHOD FOR IMPLEMENTING DUAL-HOMING - The invention discloses a method for implementing dual-homing, including: setting each one of any two core control equipment as a standby for each other, connecting a network entity belonging to one of the core control equipment with the two core control equipment through a primary link and a standby link respectively; setting the primary link connected with the core control equipment as activated, and setting the standby link connected with the core control equipment inactive; determining whether the core control equipment corresponding to the primary link is out of service, if the core control equipment corresponding to the primary link is out of service, activating the standby link; otherwise, continuously determining whether the core control equipment corresponding to the primary link is out of service. The invention also discloses another method for implementing dual-homing, by which the reliability of the network can be improved. | 05-03-2012 |

| 20090126897 | METHOD AND APPARATUS FOR SEMI-SOLID MATERIAL PROCESSING - A method of forming a material includes the steps of: vibrating a molten material at an ultrasonic frequency while cooling the material to a semi-solid state to form non-dendritic grains therein; forming the semi-solid material into a desired shape; and cooling the material to a solid state. The method makes semi-solid castings directly from molten materials (usually a metal), produces grain size usually in the range of smaller than 50 μm, and can be easily retrofitted into existing conventional forming machine. | 05-21-2009 |

| 20100220809 | Method for transmitting multi-antenna superimposed symbol and apparatus using the same - A method for transmitting symbols in a communication system, includes dividing N symbols to be transmitted at one time into 2 groups. A first processing is performed on each of a plurality of symbols in a first group in order to obtain a first group of superimposed symbols. A second processing is performed on each of a plurality of symbols in a second group to obtain a second group of superimposed symbols. Each of the first group of superimposed symbols is transmitted one by one by a first antenna, and corresponding symbols in the second group of superimposed symbols are transmitted by a second antenna. The first processing and the second processing respectively include a conjugate cancellation operation. | 09-02-2010 |
| 20110069776 | MIMO DETECTION METHOD AND SYSTEM BASED ON CHANNEL CORRELATION - An OFDM symbol detection method is disclosed, which includes: receiving OFDM modulated symbols transmitted from multiple transmitting antennas; receiving information on correlation time and/or correlation bandwidth; performing channel estimation on each of a plurality of channels for the multiple transmitting antennas, and conducting smoothing processing on each channel estimation result according to said information on correlation time and/or correlation bandwidth, so as to obtain channel estimation averages of respective channels; and performing signal detection on the received OFDM symbols by using the channel estimation averages. Both time correlation and frequency correlation are considered in the method. | 03-24-2011 |
