Design And Implementation Of Non-Signaling Calibration And Self-Loop Detection Measurements In Td-Lte Terminal Communication Test Set

With the rapid promotion of TD-LTE technique and its product development, TD-LTE terminal communication test set, investigating terminal radio frequency performance in a designated communication environment, has become an important industry development push.The subject of this thesis is the design and implementation of non-signaling calibration and self-loop detection measurements in TD-LTE terminal communication test set. Based on the subject background and significance, the main contents of this thesis are organized as follows:1. Current progress and results of the field research are stated.2. Elaborates the concept of terminal radio frequency conformance test, and describes the software and hardware architecture of the TD-LTE terminal communication test set. Then the non-signaling test environment is introduced3. The implementation of the non-signaling power calibration measurement, non-signaling frequency calibration measurement and TD-LTE terminal communication test set’s self-loop detection measurement are discussed in details. The design requirements, analysis, algorithm, test process and answer analysis such five aspects are mainly discussed. At the beginning, according to analysis about the design requirements of measurement, the certain measurement algorithm is put forward. Then the measurement will be achieved after the algorithm simulation and theoretical derivation. Ultimately, the discussion includes function verifications, accuracy contrast and efficiency contrast on account of the testing process.The research achievements has been used in the project TD-LTE terminal communication test set, widely recognized by terminal authentication organization, chip research and development enterprise and terminal manufacturers, which is commercially available.
