商业和娱乐越来越依赖于WLAN，因为它们提供了位置的灵活性和低维护工作。然而，在存在隐藏终端的情况下，由于冲突，发送器-接收器对经历严重的分组丢失。ZigZag解码已被提出作为恢复冲突分组的有效技术，但它可能导致错误传播。在本文中，我们提出了一种迭代ZigZag解码算法，以减轻错误传播，并进一步提高系统的性能，在存在冲突。仿真结果表明，该迭代ZigZag译码方法能有效地克服误码传播，显著提高系统性能。
Business and entertainment increasingly depend on WLANs, as they provide flexibility of locations and low maintenance efforts. However in the presence of hidden terminals sender-receiver pairs experience severe packet loss due to collisions. ZigZag decoding has been proposed as an effective technique for recovering collided packets, but it may cause error propagation. In this paper, we propose an iterative ZigZag decoding algorithm to mitigate error propagation and further improve the system performance in the presence of collisions. Simulation results show that the proposed iterative ZigZag decoding can effectively overcome error propagation and considerably improve the system performance.
