航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控,其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency

DWellsThesis
This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance dierence between the classications of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements.
