    摘要： Described herein are technologies pertaining to protecting user privacy in connection with attribute-based matching services. A user registers with a platform that includes a plurality of non-collaborating partitions, where registration includes transmitting a message to the platform that indicates that the user has one or more attributes corresponding thereto. Through selective encryption and a communications protocol amongst the partitions, none of the partitions are able to ascertain that the user has the attributes. Acting in conjunction, however, the plurality of partitions perform rich attribute

    摘要： A receiver circuit for estimating a state of an uplink channel between a wireless communication unit and a base station in a wireless communication system computes a conditioned Channel Impulse Response (CIR), the amount of conditioning being based on the noise present in the channel. A CIR and a Noise Variance are estimated from a Sounding Reference Signal received from the wireless communication unit. The estimated CIR is conditioned by comparing it with an adaptive threshold value selected from a look up table that lists threshold values against Noise Variance values. The threshold value further conditions the CIR to eliminate noise and interference. The conditioned CIR is converted into the frequency domain and used to provide a channel gain estimate which, together with noise estimates, is used to determine a Signal to Interference Noise Ratio (SINR) for the channel.
