technical field

The invention belongs to the technical field of wireless communication, and relates to a broadband radio frequency transceiver device for wireless communication, in particular to a software radio radio frequency transceiver device and method based on a PCIE interface.

Background technique

Software radio (SDR) technology is a wireless communication system architecture proposed in recent years. It was first developed from military communication technology. Its basic idea is to configure hardware through software to achieve flexible reconfigurable features. One of the key technical difficulties is One is the transceiver RF front-end circuit. The role of the software radio transceiver is to configure the radio frequency transceiver to work in any mode to meet the requirements of different existing and upcoming communication standards. These communication standards mainly include cellular communication systems (2G-2.5G-3G, etc.), wireless LAN communication systems (802.11a/b/g/n, etc.), wireless personal area network communication systems (Bluetooth, Zigbee, etc.), broadcast communication systems (DAB, DVB, DMB, etc.) and navigation communication systems (GPS, Galileo, GLONASS, Beidou) and so on. Obviously, each communication standard has its own different center frequency, channel bandwidth, noise index, linearity index, transmit power and so on. Therefore, the radio frequency front-end circuit of the software radio transceiver must have the configurability of a large dynamic range and meet the performance index requirements of different communication standards.

There are only a few patents or other public achievements in China about the general radio frequency transceiver used by software radio, especially virtual radio. It includes variable transmitting and receiving modules and control systems, but it only supports OFDM systems; in the patent publication number CN1349325A "Multi-Carrier Software Radio Transceiver and Its Method for Improving Smart Antenna Performance", the multi-carrier software radio transceiver The signal machine can be used in GSM, CDMA, WCDMA and other standards, and can calibrate the signal amplitude and phase between smart antennas through software and hardware to improve its amplitude and phase consistency, but it cannot support frequency division duplex FDD and time division at the same time Duplex TDD; Patent Publication No. CN102255621A "A Radio Frequency Front-End Circuit of a Software Radio Transceiver", the front-end circuit can support both FDD and TDD duplex modes, and can adjust equipment performance indicators to reduce power consumption, but This device is a radio frequency circuit only and is not intended for use with portable computers. So far, there is no virtual radio RF front-end device specifically for portable computers on the market. This is mainly because the existing software radio universal radio frequency transceiver mainly has the following deficiencies:

1) The bandwidth between the RF front-end and the baseband signal processing module is not large enough, and the delay is not small enough to meet the requirements of the next generation communication system.

2) The volume of the existing radio frequency transceiver device is relatively large, so it cannot be used as a virtual radio portable radio frequency front end of a portable computer.
