Aiming at the multi-standard and multi-system requirements of modern wireless communication systems, it is more and more important to process a large number of signals and data efficiently, quickly and relatively low-cost. The software radio technology has wireless communication by its easy modification and low cost. Technology has been upgraded to a new level of software and ease of expansion. Firstly, the GNU Radio platform, software architecture and hardware platform are described. Then, using the general software radio platform, the simulation and implementation of communication channels such as fading and drift are completed in the GNU Radio programming environment. Based on this, GNU Radio+ USRP is further designed. Transmission and reception of modulated signals of GMSK. Thereby wireless communication based on software radio platform is realized. From the experimental results, the system can transmit and receive GMSK modulated signals better.
