[0002] At present, most mobile phone signal detectors in the market are FDD working mode detectors. With the popularization of 4G mobile phone systems, it includes FDD and TDD modes, so the detectors on the market cannot accurately detect mobile phone signals in TDD mode systems, and the performance is wrong. Short reporting and detection distance
At present, the working mode of the existing TD-LTE mobile phone signal detector is continuous and uninterrupted simultaneous detection of uplink and downlink signals. As long as it is in the TD-LTE signal frequency band, the downlink signal of the base station and the uplink signal emitted by the mobile phone will also be collected by the detector. The disadvantage of this is that the receiving sensitivity cannot be too high. If the downlink base station signal is too high, it will cause malfunction. Therefore, the sensitivity of the detection system is contradictory, and the system leads to a short detection distance.

The invention discloses a TDD-LTE and FDD-LTE mobile phone uplink signal detection system, which relates to the technical field of signal detection; a TDD-LTE synchronization module automatically completes cell search and wireless signaling processing of a TD-LTE wireless network to obtain accurate TDD uplink and downlink time slot timing, uplink and downlink time slot ratio information, and output uplink and downlink time slot indication signals through the GPIO interface; TD‑SCDMA synchronization module automatically completes cell search and wireless signaling processing of TD‑SCDMA wireless network to obtain accurate TD‑SCDMA downlink time slot timing and downlink time slot information, the downlink time slot indication signal is output through the GPIO interface; the invention detects only the uplink time to start detection through the time slot control detection receiving channel, the system sensitivity meets the design requirements, and the detection distance It completely solves the malfunction of the base station downlink signal detection system.
Description
Technical field: [0001] The invention relates to a TDD-LTE and FDD-LTE mobile phone uplink signal detection system, and belongs to the technical field of signal detection. Background technique: [0002] At present, most mobile phone signal detectors in the market are detectors in FDD working mode. With the popularization of 4G mobile phone systems, it includes FDD and TDD modes, so the detectors on the market cannot accurately detect mobile phone signals in TDD mode systems, and the performance is wrong. The reporting and detection distance is close. At present, the working mode of the existing TD-LTE mobile phone signal detector is to continuously detect the uplink and downlink signals at the same time. As long as it is in the TD-LTE signal frequency band, the downlink signal of the base station and the uplink signal detector transmitted by the mobile phone will also be collected. The disadvantage of this is that the receiving sensitivity cannot be too high. If the downlin...
