Detection method and device for cell group numbers of secondary synchronization sequences of LTE (long term evolution) system

The invention discloses a detection method and device for cell group numbers of secondary synchronization sequences of an LTE (long term evolution) system. The method comprises the following steps of: receiving one group of first correlated sequences and eight groups of second correlated sequences; acquiring corresponding thresholds of the correlated sequences; respectively carrying out peak value processing on the first correlated sequences and second correlated sequences according to the thresholds, setting the values, smaller than the thresholds, of the correlated sequences to be zero, and reserving the values, not smaller than the thresholds, of correlated sequences; when the processed first correlated sequences and second correlated sequences have non-zero values, respectively seeking the maximum correlated values in the first correlated sequences and second correlated sequences and the corresponding index values; and calculating according to the index values to obtain the cell group numbers. The detection method and device disclosed by the invention have the advantages that: a process for peak value processing by utilizing the thresholds is added to the traditional detection method, thus the correlated value detected when the frequency point is wrong is filtered out, the condition of error detection when the correlated value obtained by detecting the wrong frequency point is correspondingly used as the detection result is avoided, the error detection rate is reduced and the detection accuracy is improved.

Primary cell searching method for long term evolution (LTE) system

ActiveCN102271384BReduce the number of times to interpret cell broadcast messagesReduce blindnessSynchronisation arrangementAssess restrictionResidenceIntermediate frequency
The invention discloses a primary cell searching method for a long term evolution (LTE) system. The method comprises that: user equipment (UE) generates local primary synchronous signals and local secondary synchronous signals corresponding to each frequency point according to frequency point information stored in a BA table; for each frequency point, the UE receives data and calculates correlation power values between the local primary synchronous signal of the frequency point and the received data and between the local secondary synchronous signal of the frequency point and the received data; the UE performs subsequent timing rough synchronization, timing precise synchronization, frequency rough synchronization, wireless frame synchronization, frequency precise synchronization and cell broadcast message reading processes according to an order from greater correlation power values to lower correlation power values corresponding to each frequency point; and if a cell broadcast messageis accurately read on a selected frequency point, the UE selects a cell of the frequency point for residence. By the technical scheme provided by the invention, the blindness of frequency point selection from the BA table in a primary cell searching process is reduced, and the times for reading the cell broadcast message on a wrong frequency point by the UE can be effectively reduced, thereby shortening primary cell searching time and improving primary cell searching efficiency.

A control method for an electromagnetic capacitance dual-mode touch control system

The present invention discloses a control method of an electromagnetic capacitance dual-mode touch system. The method comprises the steps that an electromagnetic pen emits a digital signal of a fixed frequency by using a micro control unit, and pen pressure data information is acquired by modulating a code; based on the pen pressure data information, an inductive coil emits an electromagnetic signal; an electromagnetic capacitance dual-mode touch apparatus receives the electromagnetic signal sent by the electromagnetic pen and a capacitance signal of a trigger screen, and a C to L port is set as a low frequency according to a preset time threshold and a time interval; if the C to L port is determined as the low frequency, an L to C port is set as the low frequency, an electromagnetic control module is in a working state, and electromagnetic signal input is detected; and if the C to L port is determined as a high frequency, a capacitance control module is in a working state, and capacitance signal input is detected. In the prior art, when the handwriting of the electromagnetic pen is acquired in a manner of analog signal, the process of acquiring the pen pressure information is usually interfered with an environment external electromagnetic interference signal, consequently, the wrong frequency is acquired or difference even frequency jitter occur. The method solves the above problems.
