Abstract: A method for assessing receiver signal reception performance during wireless beam steering operation of a radio frequency (RF) data packet signal transceiver capable of multiple input, multiple output (MIMO) operation. In response to transmissions of a sounding packet (SP) from a beamforming device (“beamformer”), a receiving device (“beamformee”) transmits a response data packet containing matrix data representing a beamforming feedback matrix (BFM) related to signal attenuation by the wireless signal path environment through which the beamformer and beamformee are communicating. Using the matrix data, a statistical variation can be computed which is indicative of signal reception performance of the beamformee.

Abstract: Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) with multiple RF signal transmitters and RF signal receivers capable of concurrent operations. Multiple successions of test data packets from a tester to respective RF signal receivers of the DUT and multiple successions of responsive DUT data packets from respective RF signal transmitters of the DUT to the tester are conveyed such that multiple RF signal transmissions, multiple RF signal receptions, or RF signal transmission and reception are performed at least partially concurrently.

Abstract: A method for enabling confirmation of expected phase shifts of radio frequency (RF) signals emitted from respective elements of an antenna array, such as a phased array antenna used for providing directional RF signal radiation patterns needed for beamforming. As a RF signal transmitted via an antenna element of the antenna array is shifted, e.g., stepped, in phase, the resulting received RF signal is monitored. Following detection of a phase shift, a sample of the received RF signal is captured and stored, e.g., for subsequent analysis, such as comparison with one or more expected signal phase differences to characterize the directivity of the transmitted signal.

Abstract: The present invention provides a method for synthesizing cationic bleach activators via a single-bath reaction, comprising steps of: separately dissolving 4-chloromethylbenoyl chloride and lactam in its respective solvent, adding an acid-binding agent to the lactam solution, next adding dropwisely 4-chloromethylbenoyl chloride solution into the lactam/acid binding-agent solution, and finally adding tertiary amine to the solution above to make a reaction solution, which is further treated with mixing and refluxing. The washed and dried final product is TBLC cationic bleach activator. The method of the present invention greatly simplifies the synthesizing process and lowers the stringency of reaction conditions for preparing cationic bleach activators (TBLC). At the same time, the present method produces TBLC cationic bleach activators with high yields, making it a suitable option for industrial production of these bleach activators.
