Abstract
Single-Sideband (SSB) modulation is now widely used for its high band efficiency and low power consumption. In anolog SSB systems, it is usually hard to achieve high performance due to many nonideal factors of anolog components and circuits, such as the I/Q channel mismatch and temperature drift. To overcome these disadvantages, a digtal SSB modulation system based on the Weaver method is designed in this paper. In this system we creatively use the onchip ADC of the ARM processor for audio sampling. Besides, the CORDIC algorithm and the folding transformation are also utilized to reduce hardware costs in the FPGA implemention. This paper mainly discusses the theory and implemention of the Weaver SSB modulation system, and shows the experimental results on actual hardware.
