| 英文摘要: |
| With the occurrence of burst interference, bit error rate ( BER) stability of the wireless commu-nication system ( WCS) always degrades significantly.To cope with it, a stability control algorithm is proposed, utilizing the stability theory of switched systems, which is specifically applicable for multi-parameter adaptive WCS with spectrum sensing ability, and it is capable of stabilizing BER within a reasonable range.Firstly, WCS is modeled as a switched system.Then, based on the multi-Lyapunov function, controlling rules are presented to enable the switched system to satisfy sta-ble condition asymptotically.Finally, analysis and numerical simulation results demonstrate that the switched WCS with the proposed controlling rules is superior to conventional power-controlled WCS with or without state feedback control in terms of stability performance. |
