摘要： A method of a tuning process for WLAN devices is to select test channels of the DUT (device under test) by utilizing the method of random sampling or sequence. Besides, the method obtains a parameter average by averaging the parameters of the already tested channels (or further includes the current test channel) of the DUT in a batch method or a recursive method. The parameter average is provided for tuning the non-tested channels of the DUT or the channel under test of the DUT.

摘要： An inverted-F antenna having a reinforced fixing structure is disclosed for benefiting antenna diversity. The inverted-F antenna is composed of a base board (such as a printed circuit board), a radiator and at least one supporting member each having a beveled fixing foot, wherein the shape of the radiator can be changed in accordance with various bending directions, such as a L shape, a U shape or a Z shape. The reinforced fixing structure of the inverted-F antenna further includes a dielectric material (such as foam adhesive) used for partially filling in the gap between the radiator and the base board, thereby reinforcing the strength of fixing each supporting member to the base board.

摘要： A device for identifying interference source in wireless communications is provided, including a correlation compound module, a matching and screening module, a statistical analysis module, and a match identification module. The correlation compound module uses the time of arrival (TOA) of the burst as the synchronization basis to compound the correlated frequency word, time difference of arrival (TDOA) word, amplitude word and angle of arrival (AOA) word to form a burst descriptor word (BDW). The matching and screening module uses the BWD to match the burst library to screen out the non-interference sources. The statistic analysis module uses the screened outcome for statistical analysis, and obtains a source discriminator file (SDF). The matching and identification module uses the SDF to search the interference source library for matching and obtains an identification result.

摘要： The present invention provides a system and method for multi-path simulation that employs a shielded anechoic chamber to avoid external electromagnetic interference and other uncontrollable transmission paths during testing, and simulates a main indirect transmission path by a reflector within the chamber. An attenuating device is used to attenuate signals, thereby simulating the signal attenuation during transmission. The shielded anechoic chamber also includes a movable platform and a turntable, both controlled by a control unit, for carrying a dipole antenna and a wireless communication device to be tested respectively. The movable platform is used to shift the antenna, thereby simulating the phase shift between a direct path and a main indirect path of the system; the turntable is used to change the reception azimuth of the communication device, thereby measuring the performance of the device in various azimuth angles.

摘要： A signal testing system is disclosed, which is capable of achieving a bi-directional wireless transmission measurement enabling mutual testing between device-under-tests and reference devices by configuring a symmetrical structure with circulators and multiplexers. Moreover, the signal testing system not only is capable of fetching signal out of a test path by the use of power dividers and then transmitting the fetched signal to a signal analyzer to be analyzed so as to enable the system to support multiple testing, but also is capable of generating a signal used for referencing by a signal synthesizer so as to enable the system to support numerous tests. In addition, both the signal analyzer and the signal synthesizer have a switch control integrated therein, which enables the signal analyzer to perform analysis on signals of different frequency bandwidth, and enables the signal synthesizer to generate signals of different frequency bandwidth as require.
