摘要： A monitoring device for a distributed antenna system including at least two node units communicatively coupled to each other transmits, to at least one target node unit among the node units, a data dump command for a first target signal passing through a first signal path in the target node unit. The monitoring device receives, from the target node unit, response data corresponding to the data dump command. The monitoring device generates first quality information indicative of the quality of the first target signal by using the response data.

摘要： Systems and techniques relating to beamforming testing for wireless communication are described. A described technique includes controlling a first wireless device to deactivate or activate a beamforming mode, the first device being configured to selectively use the beamforming mode to transmit data over multiple antennas; causing the first device to send a first portion of data traffic to a second wireless device via a wireless channel while the beamforming mode is deactivated; measuring first throughput values of the first portion of data traffic while the beamforming mode is deactivated; causing the first device to send a second portion of data traffic to the second device via the wireless channel while the beamforming mode is activated; measuring second throughput values of the second portion of the data traffic while the beamforming mode is activated; and producing a test result based on a comparison of the first and second throughput values, and predetermined criteria.

摘要： A receiver receives an inter-symbol correlated (ISC) signal with information symbols and a corresponding parity symbol. Values of information symbols are estimated utilizing parity samples that are generated from the parity symbols. One or more maximum likelihood (ML) decoding metrics are generated for the information symbols. One or more estimations are generated for the information symbols based on the one or more ML decoding metrics. A parity metric is generated for each of the one or more generated estimations of the information symbols. The parity metric is generated by summing a plurality of values of one of the generated estimations to generate a sum, and wrapping the sum to obtain a parity check value that is within the boundaries of a symbol constellation utilized in generating the information symbols.
