| 20110026514 | DMR PRIVATE NETWORK COMMUNICATION TERMINAL, COMMUNICATION SYSTEM, AND IMPLEMENTATION METHOD THEREOF - The present invention relates to private network communication techniques, and provides a DMR private network communication terminal, communication system, and an implementation method thereof with respect to the drawback existing in the prior art that the idle time slot can not be determined in advance, and therefore the idle time slot can not be utilized to initiate new private network communication. The DMR private network communication terminal includes: a communication module, adapted to receive/transmit DMR private network communication; a synchronization module, adapted to listen to a DMR synchronization pattern and establish synchronization with the DMR synchronization pattern, determine the time slot occupied by the DMR synchronization pattern, and thereby lock the pre-assigned communication time slot, and controls the communication module to receive/transmit DMR private network communication in the pre-assigned time slot. The present invention further provides a DMR private network communication system and an implementation method thereof. By restricting private network communication terminals to perform communication only in the preset communication time slot, the same channel of private network communication is assured to be transmitted in the same time slot. Thus, other terminals can lock the idle time slot in advance and initiate new private network communication, and therefore the DMR frequency spectrum resource can be fully utilized. | 02-03-2011 |
| 20100318883 | Method for Enhancing Reliability of Information Transmission - The present invention provides a method for enhancing reliability of information transmission, comprising the steps of: (a) establishing a matrix based on the length of bits of valid information in frame time slots; and creating a new matrix by presetting Error Correction Coding (ECC) for rows and columns of said matrix; (b) adopting the 1st Interleaving method to re-allocate bits which have been processed twice by using said ECC in said new matrix, to both ends of said frame time slots; and (c) adopting the 2nd Interleaving method to re-allocate the remaining bits in said new matrix to the middle of said frame time slots. After processed like this, the anti-interfering ability of the bits at both ends of TDMA frame time slot can be significantly enhanced, and the bit-error rate is decreased most, and all redundancy bits of Hamming codes can be arrayed at both ends of TDMA frame time slot. | 12-16-2010 |
| 20090197545 | Radio with a Key and Knob Combination - The present invention relates to a radio with a key and knob combination. To solve problems such as inconvenience caused by the independent PTT key and volume control knob on the traditional radios, the present invention provides a radio with a key and knob combination, comprising a PPT key unit and a volume control unit, wherein the key is installed inside a central cavity of the knob, which is a hollow knob, to form the key and knob combination. Rotation of the knob ( | 08-06-2009 |
| 20080254349 | Battery Latch Structure - The present invention discloses a battery latch structure, wherein a battery slot for receiving a battery is located on the main body, a first end of said battery is latched to a first end of said slot through a first clamp structure, and a second end of said battery is latched to a second end of said slot through a second clamp structure. The second clamp structure includes a second fixed clamp located on the left and right sides of the second end of said slot, and a battery latch, a spring and two battery lock members located at the second end of said battery. The battery latch is located at the second end of the battery and may be slid upwards and downwards to be moveably connected with the two battery lock members. The spring is located between the two battery lock members. The said spring can push the two battery lock members protruding leftwards and rightwards respectively to insert into the second clamp. The said battery latch can be moved upwards by the action of outside force, to release the two battery lock members from the second clamp. The advantages of the present invention are simple in structure and convenient for operation. | 10-16-2008 |
