一种用于卫星通信的自适应编码调制信号接收方法
A Receiving Method for Adaptive Coding and Modulation Signal in Satellite Communication
摘要
Abstract
For adaptive coding and modulation signal receiving,switching demodulation mode is apt to in-terrupt the signal reception and causes undesired data discontinuity using regular receiving methods. To mitigate the disadvantage,a new adaptive receiving method is presented. This method uses a unified de-modulation structure to realize the continuous track of various modulation signals. A correlation value of frame-synchronization-word( FSW) wave is measured between the FSW modulation wave saved in the re-ceiving terminal and the FSW wave in the received signal to implement the estimation and compensation of the phase error during the switch of demodulation modes. The continuous track of frame synchronization is consequently achieved. The simulations demonstrate the feasibility of the presented method.关键词
