Abstract: The present disclosure relates to a method and apparatus for pushing subscription data in Internet of things. The method includes: parsing a subscription condition set into a first attribute set in response to receiving the subscription condition set; acquiring device data; parsing the device data into a second attribute set; performing Bloom filtering on attribute elements in the second attribute set one by one in a predetermined order by taking an attribute element set in the first attribute set as a filter condition; stopping the Bloom filtering on the other attribute elements in the second attribute set in the case that a Bloom filtering result of one attribute element indicates an occurrence of mismatch; and returning to the step of acquiring the device data.

Abstract: Present application provides embodiments of a transmitter and an interference cancellation method. The transmitter includes: a first digital predistorter (DPD), a power amplifier (PA), and a first processor located on a feedback channel of the transmitter and separately connected to the PA and the first DPD. The first processor performs, according to a feedback cancellation signal, interference cancellation on a signal of the feedback channel, to acquire a first mixed signal, and sends the first mixed signal to the first DPD. The first DPD is configured to perform linear predistortion processing according to a first baseband signal on a first transmit channel and the first mixed signal, to generate a first predistortion signal. The PA is configured to amplify and then transmit a to-be-transmitted signal using an antenna. The to-be-transmitted signal is the first predistortion signal or a signal obtained according to the first predistortion signal.
