Title:
CONSTANT ENVELOPE MULTIPLEXING APPARATUS AND METHOD FOR THREE SAME POWER SIGNALS
Document Type and Number:
WIPO Patent Application WO/2023/243769
Kind Code:
A1
Abstract:
Disclosed are a constant envelope multiplexing apparatus and method for the three same power signals for satellite navigation signal generation and transmission system. The constant envelope multiplexing apparatus comprises: a signal generator for generating a first satellite navigation signal, a second satellite navigation signal, and a third satellite navigation signal; a modulator that modulates signals having the same phase to different chip pulse waveforms, the signals being generated by setting the amplitude and phase of an in-phase component and the amplitude and phase of a quadrature phase component on the basis of relationships between sample absolute values respectively corresponding to variable instantaneous power of the first to third satellite navigation signals; and a multiplexer for performing constant envelope multiplexing on satellite navigation signals modulated by the modulator, wherein the sample absolute value of the first satellite navigation signal and the sample absolute value of the second satellite navigation signal have a first value and a second value each with frequency of 0.5 during chip pulse modulation of the modulator.
