| 摘 要： | 论述了消除无线移动通信反馈和重发的随机存取协议.在传统的Aloha协议中用可删除修正编码替换重发信息来维持18.4%的信道吞吐量,而本文提出采用纠错编码替代可删除修正编码实现无反馈和重发,至少可以控制32.2%的信道吞吐量.

| Abstract: | It is desirable in random|access protocols for wireless mobile communications to avoid the need for feedback and retransmissions. Pure Aloha protocol using erasure correction coding in place of retransmissions can maintain a throughput of 0.184. If we use error|correction coding(instead of erasure correction coding), throughput levels not less than 0.322 can be realized for asynchronous random access without feedback or retransmissions. |
