The invention discloses a radio
fiber connection interface communication
library based on a FPGA and a realization method thereof. The radio
fiber connection interface communication
library makes the FPGA connect with a universal
software-defined radio
peripheral through an
optical fiber interface. The radio
fiber connection interface communication
library comprises an
external interface and an internal module. Through the
external interface, the radio fiber connection interface communication library is connected with a
wireless local area network reconfigurable
physical layer and the radio
peripheral. The internal module comprises a
peripheral management module, a packager, a fiber interface module, an unpacking device, and a
data transmission module. Through using a high-speed low-
delay data transmission method, a dynamic
radio frequency parameter configuring method, a flow control method based on speed, and a
clock domain
conversion method based on FIFO and other methods, the radio fiber connection interface communication library and the method solve connection problems of a
software-defined radio development platform based on the FPGA and the radio peripheral, and communication library and the method are characterized by high speed,
low delay, easy configuration, and support multi-sampling rate and
user defined clock domain.
