Title:
UP-CONVERSION FREQUENCY MIXING METHOD AND DIGITAL TRANSMITTER ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO/2024/007454
Kind Code:
A1
Abstract:
The present disclosure provides an up-conversion frequency mixing method and a digital transmitter architecture, the method comprising: using each phase in a 2n phase local oscillator IQ digital signal to respectively perform up-conversion frequency mixing processing on an in-phase baseband digital signal and a quadrature baseband digital signal that are simultaneously received, and obtaining a 2n phase up-conversion frequency mixed signal, n being an integer, n ≥ 2, and the phases of any two phases of the local oscillator IQ digital signals being different. The present disclosure can effectively relieve the problem of severe modulation harmonics.
