A heterogeneous processing system for federated learning and privacy-preserving computation, including: a serial subsystem configured for distributing processing tasks and configuration information of processing tasks, the processing task indicating performing an operation corresponding to computing mode on one or more operands; and a parallel subsystem configured for, based on the configuration information, selectively obtaining at least one operand of the one or more operands from an intermediate result section on the parallel subsystem while obtaining remaining operand(s) of the one or more operands with respect to the at least one operand from the serial subsystem, and performing the operation on the operands obtained based on the configuration information.

Heterogeneous processing system for federated learning and privacy-preserving computation

The present disclosure relates to correction apparatus and correction methods. One example correction apparatus includes a first adjustment module, a plurality of second adjustment modules, a correction calculation module, and a plurality of non-ideal channels. One second adjustment module is disposed on one non-ideal channel. The first adjustment module is connected to each non-ideal channel. The correction calculation module is separately connected to the first adjustment module and the plurality of second adjustment modules. The correction calculation module is connected to an output end of each non-ideal channel. The non-ideal channel is a channel that outputs an output signal in response to a drive signal having an error value.

Correction apparatus and correction method

Embodiments of the present invention disclose a beamforming method, a receiver, a transmitter, and a system. The beamforming method includes: controlling, according to a preset rule, connection or disconnection of N analog channels corresponding to N antenna array elements, to obtain an independently received equivalent signal at each of the N antenna array elements, where N is a natural number greater than or equal to 2; obtaining, based on the independently received equivalent signal at each of the N antenna array elements, a beamforming weight; and sending the beamforming weight to a transmitter. According to the embodiments of the present invention, costs can be reduced, and relatively good interference suppression performance can be obtained.

Beamforming method, receiver, transmitter, and system

Embodiments of the present invention disclose a method and an apparatus for transmitting data. The apparatus for transmitting data includes a high frequency radio unit HFRU that is in a communication connection with a site, and a shift frequency radio unit SFRU that is in a communication connection with the HFRU and with a user equipment, where the HFRU includes a high frequency radio unit&#x2014;indoor device unit HFRU-IDU and a high frequency radio unit&#x2014;outdoor device unit HFRU-ODU that connects to the HFRU-IDU, and the SFRU includes a high frequency band transceiver and a wireless cellular band transceiver. By converting to-be-transmitted data into intermediate frequency signals for transmission, the method and apparatus for transmitting data according to the embodiments of the present invention can remarkably reduce a data transmission bandwidth, thereby saving bandwidth resources, reducing a data transmission cost, and reducing a device deployment cost.
