    摘要: A hybrid monitoring-sleeping method of wireless sensor and the wireless sensor are provided by the present invention, during N (N= N1+N2) monitoring-sleeping period, the wireless sensor monitors with the first monitoring duration, the wake-up data packet transmitted by the data acquisitor or the mobile terminal in the N1 monitoring-sleeping periods, and the wireless sensor monitors with the second monitoring duration, the wake-up data packet transmitted by the mobile terminal in the remaining N2 monitoring-sleeping periods. The first monitoring duration is longer than the second monitoring duration, N1 is less than or equal to N2, and the N1 first monitoring duration and the N2 second monitoring duration are alternatively distributed. Compared with the single monitoring duration used in the prior art, the total monitoring duration of the N monitoring-sleeping periods is reduced, as a result, the monitoring power consumption of the wireless sensor is also reduced.

    摘要: A channel decoding method and decoder are disclosed. The decoding method is based on a Circular Viterbi Algorithm (CVA), rules out impossible initial states one by one through iterations according the received soft information sequence, and finally finds the global optimal tail-biting path. In the present invention, all impossible iterations are ruled out through multiple iterations, and only the initial state having most likelihood with the received sequence survives. The algorithm is finally convergent to an optimal tail-biting path to be output. In addition, the method also updates a metric of a maximum likelihood tail-biting path (MLTBP) or rules out impossible initial states through the obtained surviving tail-biting path, thereby effectively solving the problem that the algorithm is not convergent due to a circular trap, providing a practical optimal decoding algorithm for a tail-biting convolutional code, reducing the complexity of an existing decoding scheme, and saving the storage space.

    摘要: Disclosed is a robust downlink timing synchronization method in an LTE system, which includes: step 1: a receiving terminal continuously storing time domain signal sequences of M PSS transmission periods; step 2: performing narrowband filtering on the time domain signal sequences of the M PSS transmission periods; step 3: performing down-sampling on data obtained after the filtering; step 4: performing sliding differential mirror correlation on the down-sampling data of an m th PSS transmission period to obtain a correlation value of an i th instant; step 5: superposing correlation results to obtain a superposition result; and step 6: determining whether the superposition result has an obvious peak interval; if yes, completing capturing the primary synchronization signal, and obtaining timing information according to a position of a maximum correlation peak; otherwise, returning to step 1. The present invention effectively reduces the influence of initial frequency offset and ensures the timing synchronization in a low signal-to-noise ratio interval. The present invention has fine utility under the receiving conditions where the initial frequency offset is not compensated and the channel transmission environment is unknown, and has good robustness.

    摘要: The present invention provides an authorized shared access (ASA) assisted interference coordination method in a heterogeneous time-division duplexing (TDD) relay network. In a TDD relay system architecture, an ASA controller assists a secondary system to perform an interference coordination mechanism by adjusting a time slot structure configuration and synchronization information, and a mobility management entity (MME) obtains a time slot configuration and the synchronization information of a primary system through ASA, and selects, according to relevant information of a relay node inside a management range, an optimal time slot configuration and a working mode for the relay node. The ASA assisted interference coordination method in a heterogeneous TDD relay network of the present invention can effectively avoid interference on a primary user from the secondary system and increase a spectrum utilization rate; meanwhile, a relay node continues working on an ASA carrier frequency f1, thereby avoiding signaling consumption and reduction in network performance caused by switching of the relay node and a large number of relay user equipment (relay user equipment, RUE).

    摘要: The present invention discloses a method for fusing baseband resources between networks of different standards. The method includes the following steps: performing coding on baseband data by using a coding scheme of a first network, and then performing modulation by using a modulation scheme of a second network.
