| 摘 要： | 提出在未来无线家庭网中采用合作分集的思想,通信时利用处于空闲状态的终端用户对所发送信息进行中继发送,保证整个网络误码率性能、中断概率以及发送功率达到最佳折衷.在Nakagami平衰落信道条件下研究了再生中继和非再生中继两种合作方式下的中断概率和误码率性能,给出误码率和中断概率的解析表达式,并用matlaab进行仿真,仿真结果表明,在低信噪比条件下再生中继大大优于非再生中继方式,但高信噪比条件下两者性能接近. |
| 关 键 词： | 无线家庭网络 合作分集 再生中继非再生中继 |

| Abstract: | The idea of multi-hop relay cooperative diversity is presented, which utilize any free terminals to relay the transmitted data to insure the optimal tradeoff among the total power, the probability of error rate and the outrage probability. In the Nakagami fiat fading channel condition ,the outrage probability and the BER performance are analisised in nonregenerate and regenerate relay .The simulation result show regenerate relay system outperform nonregenerate relay system for low and moderate SNR,while have similar performance at high SNRS . |
| Keywords: | Wireless home network Cooperative diversity Generate relay Nongenerate relay |
