20150200798 | METHOD OF TRANSMITTING PILOT BITS IN A WIRELESS COMMUNICATION SYSTEM - A method of allocating pilot bits in a wireless communication system using a multiple carrier modulation (MCM) is disclosed. The method includes allocating a plurality of precoded data symbols precoded by a precoding matrix module and a plurality of non-precoded pilot bits to a plurality of subcarriers, and transmitting the allocated precoded data symbols and the allocated non-precoded pilot bits. | 2015-07-16 |
20150200799 | METHOD AND RECEIVER FOR RECEIVING A COMPOSITE SIGNAL - A data processor selects a set of BOC correlations in accordance with a BOC correlation function for the sampling period if the primary amplitude exceeds or equals the secondary amplitude for the sampling period. The data processor selects a set of QBOC correlations in accordance with a QBOC correlation function for the sampling period if the secondary amplitude exceeds the primary amplitude for the sampling period. The data processor uses either the BOC correlation function or the QBOC correlation function, whichever with greater amplitude, at each sampling period to provide an aggregate correlation function that supports unambiguous code acquisition of the received signal. | 2015-07-16 |
20150200800 | METHOD AND RECEIVER FOR RECEIVING A COMPOSITE SIGNAL - A data processor selects a set of BOC correlations in accordance with a BOC correlation function for the sampling period if the primary amplitude exceeds or equals the secondary amplitude for the sampling period. An electronic data processor determines whether the receiver is operating in a steady-state mode by evaluating the detected primary amplitude. The data processor selects and/or processes a set of BOC correlations for the sampling period to track a carrier of the received composite signal if the receiver is operating in the steady-state mode. In one embodiment, the data processor forms a first code error using the selected BOC correlations with a first chip spacing to drive the code tracking. | 2015-07-16 |
20150200801 | Personal area network management method and personal area network system - A Personal Area Network (PN) management method is disclosed. The method includes that a PN manager is set for a PN to manage the PN. Correspondingly, a PN system is disclosed. By the method and system, a user can set a PN manager and managed PN equipment of his/her own PN according to his/her own needs, and when a large amount of equipment exists in the PN, some PN equipment in the PN can be conveniently, rapidly and effectively managed through the PN manager. | 2015-07-16 |
