We present a blind collision resolution algorithm in slow fading channels based on retransmission diversity. The algorithm neither assumes packet nor symbol synchronization of the different users and it does not demand estimates of the arrival times of the collided signals. The proposed scheme works independently of the relative alignment of the packets, so it can also resolve synchronous collisions. The decoding complexity does not scale with the packet size and thus does not burden the receiver. In the blocking mode, the algorithm achieves high throughput and low queuing delay similar to synchronous network division multiple access (NDMA) protocols. In the non-blocking mode, there is longer queuing delay of the packets before transmission, but the throughput is still high due to faster accumulation of the buffered packets at the transmitters.

异步盲网络辅助分集多址接入


我们提出了一种基于重传分集的慢衰落信道中的盲冲突解决算法。该算法既不假设不同用户的分组同步或符号同步，也不要求估计冲突信号的到达时间。所提出的方案独立于数据包的相对对齐而工作，因此它还可以解决同步冲突。解码复杂度不随数据包大小而变化，因此不会给接收器带来负担。在阻塞模式下，该算法实现了类似于同步网络分多址（NDMA）协议的高吞吐量和低排队延迟。在非阻塞模式下，数据包在传输前的排队延迟较长，但由于发送器处缓冲数据包的累积速度较快，因此吞吐量仍然很高。
