Design of High-Performance Broadband Signal Generation Algorithm Based on Memory

The signal generation algorithm capable of realizing arbitrary controllable characteristic parameters of signals can be widely used in the field of testing communication equipment. With the development of technology, the signal form applied in the test process is more and more complex, and the signal bandwidth is wider and wider. And the quality requirements for signals are also increasing. Therefore, the high- performance broadband signal generation algorithm with arbitrary controllable characteristic parameters has high research value. This paper proposes a high-performance broadband signal generation algorithm based on FPGA and external memory. This method is applied to generate any bandwidth signal up to 560MHz. The spurious suppression is larger than 50dBc, and the generated communication signal EVM is better than 1.6%. The algorithm has a wide range of application scenarios in the measurement of satellite communication equipment, mobile communication equipment and military communication equipment.
