Acquisition procedure uplink synchronization for mobile WiMAX analyzer system.

摘要

A method of acquiring synchronization Uplink, UL, for an analyzer mobile WiMax system, the process being performed when received in advance a sub-frame DL containing information of a Connection Identifier, CID, assigned and stored in advance a Portable Subscriber Station, PSS, which has a function test mode to create a sub-frame UL by an analyzer mobile WiMax system having a means of signal generation (200) configured to store information CID in advance and analyzing means signal (300) configured to receive and analyze the sub-frame UL, without requiring a procedure of network entry in conjunction with an access Station Radio, RAS, comprising procedure: step (a) generating means of the signal (200) that converts D / a continuously, RF-modulates and outputs the DL sub-frame (510, 512) obtained by encoding data (52) including a cell identification, ID, previously known by means of analysis of the signal (300), the CID information stored in the PSS and at least one frame number: step (b) means for analyzing the signal (300) which receives the sub-frame UL, which is created through encoding of data known test on the cell ID and the frame number, is RF modulated and removed through the PSS (520, 522); step (c) the means of analysis of the signal (300) that continuously demodulates, performs A / D conversion and data capture compressing subframe UL modulated to a predetermined extent so that the temporary amount of UL subframes exceeds that of at least one frame (524, 526); and step (d) the means of analysis of the signal (300) that acquires UL synchronization by comparing the UL sub-frame created by encoding the known test data based on the cell ID and the frame number and stored advance with the data captured at step (c), using a technique of correlation in time (532).
