| 摘 要： | 介绍半盲最小均方平滑算法(LSS),仅利用冲突时隙中接收到的信号,根据信道阶数逐个分辨出发生冲突的用户数据包。该算法避免了冲突数据包的重传,提高了网络吞吐量,降低了延时。

| Abstract: | A semi-blind LSS method was proposed in this paper to solve peckets collision problem in Ad hoc networks.This method can resolve the collision successively only with the signals received in the collision slot. It avoid packets retransmission, so that it improves networks throughput and reduces transmission delay. Compared with the training-based method, it requires fewer known symbols and has part resolvability. |
