| 摘 要： | 提出一种用于多载波蜂窝移动通信系统的子信道合并切换算法。采用多维Markov链对子信道合并切换算法进行系统建模分析,得到了呼叫阻塞率、切换阻塞率等关键系统性能参数的解析结果。与切换保护信道算法相比,子信道合并切换算法在对其他类型呼叫性能影响很小的前提下,改善了对带宽要求较高的业务的切换性能。该算法还可以与其他资源预留切换算法相结合,改善其性能。

| Abstract: | A novel handoff algorithm named sub-channel combination(SCHC) handoff algorithm used in multi-carrier cellular mobile communication system was proposed.Multi-dimensional Markov chain was used to analyze the perform-ances of SCHC handoff algorithm.Analytical results of the key parameters such as handoff blocking probability were ana-lytically obtained.The analysis shows that the proposed scheme of sub-channel combination improves the handoff perform-ance as compared with the guard channel algorithm.The handoff blocking probability for the bandwidth consuming service is decreased while the other communication quality remains unchanged during the handoff.The sub-channel combination scheme can also work with the other resource reservation handoff schemes to improve their performances. |
