Research on FPGA-based Sine Wave Transmitter

Abstract

Abstract This paper touches on a sine wave transmitting mode being designed applicable to multichannel high-power electromagnetic transmitters, well explaining the design scheme and working principle of each module. With FPGA as the core to build the hardware platform and DSP as a bridge to the cooperation between the upper computer and the FPGA lower computer, this very mode amplifies the MSK signal provided by the external interface with power and makes it featured high-power, high-energy efficiency as well as frequency accuracy, realizing the transmitting current as 0.01Hz~300Hz standard sine wave and MSK modulated wave output.
