Abstract

The invention provides a wideband signal digital frequency selecting system with self-adaptive bandwidth adjustment and a signal processing method. The system comprises an OMC subsystem, an ADC subsystem, a wideband digital medium frequency processing subsystem, an MCU control subsystem and a D / A converter, wherein the OMC subsystem is connected with the MCU control subsystem; the MCU control subsystem is also connected with the ADC subsystem, the wideband digital medium frequency processing subsystem and the D / A converter respectively; and the ADC subsystem, the wideband digital medium frequency processing subsystem and the D / A converter are connected in sequence. Owing to the self-adaptive bandwidth adjustment function, the system can adapt to the bandwidth signal digital frequency selection function with different bandwidths, meet mobile communication systems with different bandwidths and be suitable for various digital repeater systems, the carrier pond dispatching system, the digital radio frequency remote system, the base station subsystem and the like; and the miniaturization of the digital frequency selecting system with the self-adaptive bandwidth adjustment is easy to realize.

Description

technical field [0001] The invention relates to the technical field of broadband signal digital frequency selection, in particular to a broadband signal digital frequency selection system and a signal processing method with an adaptive bandwidth adjustment function. Background technique [0002] At present, in the base stations, base station subsystems, remote base station systems, repeaters and carrier scheduling systems of GSM, CDMA, TD-SCDMA, WCDMA and other communication systems, the bandwidth is generally fixed and cannot be adjusted. In this way, the bandwidth requirements of different operators cannot be met. Every time the bandwidth is modified, a new system needs to be reconfigured. The flexibility is very poor, and the product reusability is very poor. [0003] Moreover, nowadays, a variety of communication systems coexist, and the update period of the communication system is gradually shortened. Different communication systems have different carrier bandwidths and...
