Abstract: A carrier configuration method and system for a distributed antenna system, a processing device, and a chip are provided. The distributed antenna system includes at least one access unit and at least one remote unit. The method includes: acquiring a configuration parameter of a carrier to be transmitted of at least one access unit, the configuration parameter including a mapping relationship between the at least one access unit and the at least one remote unit; and establishing a transmission channel between the at least one access unit and the at least one remote unit according to the mapping relationship.

Abstract: The present application relates to a system and a method for reducing a signal peak-to-average ratio, and a computer-readable storage medium. Before the peaks in the IQ signal are scaled, a scaling effect of peak points scaling on subsequent peak points is estimated and windowing intensities of subsequent peak points are modified. It solves a problem that generated correction coefficients superimpose on top of each other leading to excessive peak shaving. In addition, the above method does not need a lot of multipliers and is easy to be implemented.

Abstract: A method of achieving synchronization management of account information of a World Wide Web (WEB) interface in a multi-system Distributed Antenna System (DAS) is provided, including: a security verification initialization of the WEB interface when a single system device in the multi-system DAS is started, a current user information synchronization of a WEB interface between systems in the multi-system DAS, and a key book synchronization of WEB account information between the systems in the multi-system DAS. With the adoption of the method, synchronization management of the account information of the WEB interface in the multi-system DAS may be achieved, so that a management mode is simplified, and management efficiency is improved, information of a current WEB user is synchronized, integration of WEB user statuses and automatic login of multiple systems are achieved.
