Application of multicarrier 2-dimension spread spectrum (MC-2D-SS) is proposed in the field of aerospace TT&C systems to enhance their resistance to interference during mission operations. In principle, MC-2D-SS is the combination of direct sequence spread spectrum (DS-SS) and multicarrier CDMA (MC-CDMA). Therefore, it has both the characteristics of signal hiding of DS-SS and anti-inter-symbol interference (ISI) and anti-interference of MC-CDMA. A design of transmitter and receiver using MC-2D-SS is given for aerospace TT&C. Discussion is given to key technical issues of design, e.g. synchronization, ranging, anti interference and channel estimation, and a rough synchronization scheme is recommended. As a result, the TT&C system not only fully meets mission operation requirements, but also has high spread spectrum gain, strong anti-interference performance, ISI resistance capability and adaptive transmission characteristics.
