A multi-band multi-path receiving and transmitting device and method, and a base station system are provided. The multi-band multi-path receiving and transmitting device includes a broadband antenna, at least two multi-frequency couplers, a multi-band transceiver, and a signal processing module. The multi-band transceiver is adopted to decrease the number of the transceivers, thereby reducing the material cost and the mounting cost of the base station system.

A multi-band multi-path receiving and transmitting device and method are provided. The multi-band multi-path receiving and transmitting device includes at least two multi-frequency couplers, a multi-band transceiver, and a signal processing module. The multi-band transceiver includes at least two first frequency band receiving branches and at least two second frequency band receiving branches, and the multi-band transceiver is adopted to decrease the number of the transceivers, thereby reducing the material cost and the mounting cost of the base station system.

The present invention is applicable to the field of communication, and provides an analog digital data conversion method, an analog digital data convertor and an analog digital conversion chip. The method includes: converting multiple groups of analog data to multiple groups of digital data; performing frequency shift on the multiple groups of digital data, wherein the multiple groups of frequency shifted digital data are independently distributed within a first preset bandwidth; filtering the multiple groups of frequency shifted digital data to remove outband information; and distributing without overlap the filtered multiple groups of digital data within a second preset bandwidth. The method substantially reduces pressure of data transmission between the converter and an FPGA or ASIC, and effectively simplifying the design of a multiband receiver.

Analog digital data conversion method, analog digital data converter, and analog digital conversion chip

A method, device, and system for communication signal transmission are provided, which relate to the field of communications, so as to improve reception performance of the network. The method includes dividing, by a multi-frequency receiver, Radio Frequency (RF) signals by frequency bands received from an antenna to obtain RF signals of different frequency bands; sending a first group of RF signals of a predetermined frequency band to an RF unit so that the RF unit converts the received first group of the RF signals of the predetermined frequency band into first baseband digital signals and sends the first baseband digital signals to a baseband processing unit; and converting a second group of the RF signals of the predetermined frequency band into second baseband digital signals and sending the second baseband digital signals to the baseband processing unit by using a digital baseband interface.
