Synchronization of direct-RF receiver in software defined radio platform

Abstract

Software defined radio is increasingly important due to its flexibility to integrate a variety of communication standards and efficiency to develop or verify system architectures and algorithms. Here we provide a general platform with hardware acceleration IPs in FPGA to speed up the routine computing jobs like filters or FFT. Meanwhile, different frequency bands need different RF modules in the past, now we can use an ultra-highspeed ADC to sample RF data and down convert them by digital RF technology. Also, we develop the acquisition-tracking method to overcome the timing and frequency offset by software to replace lots of analog hardware components and IC works.
