摘要：

It is desirable in random-access protocols for wireless mobile communications to avoid the need for feedback and retransmissions. Pure Aloha protocol can use erasure correction coding in place of retransmissions to maintain a throughput of 0.184. We show in this note that if we use error-correction coding (instead of erasure correction coding) throughput levels not less than 0.322 ran be realized for asynchronous random access without feedback or retransmissions.
