General modulation and demodulation based on SoPC

This paper focuses on the design method of general modulation and demodulation for SDR(software defined radio).Combined with the performance requirements of SDR,a kind of modulation and demodulation is presented in detail,which is based on SoPC technology and CORDIC algorithm.Finally,the system achieves SoPC HW-SW(hardwaresoftware)co-design.The results indicate that this system has strong points such as simple structure and low cost,fully shows the flexibility and open characteristic of SDR,and meets practical application.
