Abstract: The present disclosure relates to an uplink summation method and device, and a distributed antenna system. The method comprises: acquiring uplink CPRI data streams of a channel of an AU or an EU in a system, performing bit width extension on the CPRI data streams, and performing full precision summation; extracting an orthogonal IQ signal in the CPRI data streams after summation, and determining a reference value and a detected value of the IQ signal so as to determine attenuation values corresponding to fast fading and slow amplification of the IQ signal; generating a gain table corresponding to CPRI data according to carrier mapping information of the system and the attenuation values; and shifting the IQ signal in the CPRI data streams according to the gain table, and truncating the shifted IQ signal with a preconfigured bit width.

Abstract: Provided are a cleaning device and a control method thereof. The cleaning device includes: a main body, including a suction unit generating a suction air flow, used for collecting an object to be cleaned up through the suction air flow; an interaction element, arranged on the main body and exposed outside, and used for generating, in response to an interaction event triggered by a user, an indication signal based on an interaction gesture sensed in the interaction event; and a second controller, arranged in the main body and coupled with the interaction element, and used for acquiring the indication signal and sending, according to the indication signal, a corresponding given signal to the suction unit such that the suction unit works according to the given signal.
