非再生式星上处理和程控交换及其支持IP业务的可能性

星上处理技术对提高卫星通信的传输质量和频谱利用率起着关键性的作用，已经成为卫星通信领域研究的热点。再生式星上处理虽然优点显著，但其技术难度大、设备复杂度高及应用灵活性小，系统容量也受到设备复杂度的限制。针对再生式星上处理的一些不足，本文通过将连续波时分复用技术和程控电路交换相结合，提出一种非再生式星上处理和交换技术，并论证了其支持IP业务的可能性。得出结论:基于连续波时分复用和程控电路交换相结合的中继设备能够实现强实时性IP业务的一跳传输，在一定程度上提高了卫星通信系统的通信容量，降低了卫星设备复杂度。 

On-board Non-regenerating Processing and Stored Program Controlled Switching and its Possibility of supporting IP services

On-board processing technology plays an important role in improving the quality of transmission and spectrum efficiency in satellite communications, and has become a new research hotspot in the satellite communications field. Though regenerative on-board processing technology has significant advantages, it suffers from drawbacks such as great technical difficulty, high complexity of equipment and low flexibility. The capacity of satellite communication systems is also limited by the complexity of equipment. To overcome these drawbacks, a non-regenerating processing technology, which combines Continuous Wave Time-Division-Multiplexing technology and program-controlled circuit switching, was proposed. The possibility of supporting IP services was testified. The conclusion was that one-hop transmission of the strong real-time IP services can be realized by the relaying equipment based on Continuous Wave Time-Division-Multiplexing and stored program controlled circuit switching, the capacity of satellite communication systems can be improved and the complexity of the satellite equipment can be reduced.
