一种通用软件无线电系统外设装置 技术领域  Universal software radio system peripheral device
本发明涉及软件无线电领域， 尤其涉及一种通用软件无线电外设的装置。 背景技术  The present invention relates to the field of software radio, and in particular to a device for a general software radio peripheral. Background technique
目前的软件无线电有两大类， 一类是基于传统的可编程器件的， 如 DSP ( Digital Signal Processer )、 FPGA ( Field - Programmable Gate Array, 现场可 编程门阵列 ), 另一类是基于 PC ( Personal Computer, 个人计算机） 架构的， 目前最流行的处理方式是通过 CPU (中央处理器， Central Processing Unit )进 行信号处理。 两者都需要一种通用的软件无线电外设， 用于接收和发射信号， 另外， 由于无线通信未来的发展趋势是多天线、 大带宽， 要求处理的速率越来 越高， 因此， 要求的对外接口的速率也有很强的需求， 因此， 通用外设面临着 升级换代的问题， 这点上， 无论是目前的 USRP ( Universal Software Radio Peripheral软件无线电通用外设）还是微软的 SORA ( SOFT WIRE RADIO, 软 件无线电）平台， 做的都不好。  There are two major types of software radios, one based on traditional programmable devices, such as DSP (Digital Signal Processer), FPGA (Field-Programmable Gate Array), and PC-based (the field-programmable gate array). Personal Computer, Personal Computer) Architecture, the most popular processing method at present is signal processing via CPU (Central Processing Unit). Both require a general-purpose software radio peripheral for receiving and transmitting signals. In addition, since the future development trend of wireless communication is multi-antenna, large bandwidth, and the processing speed is required to be higher, the required external There is also a strong demand for interface speeds. Therefore, general-purpose peripherals face the problem of upgrading.

Figure imgf000002_0001
The channel and sampling sections cannot be extended to many channels, the sampling part can not be extended to multiple channels.
可以看出， USRP和 SORA的射频可扩展性很差， 另外， 其应用领域单一， 仅能应用于 PC领域， 因此， 为了适应以后的处理信号的需求， 一种开放性强 的、 升级能力灵活的、 具有多平台适用性的通用外设平台具有存在的需求。 发明内容  It can be seen that the RF scalability of USRP and SORA is very poor.
