Burst erasure correction to improve the efficiency of broadband CSMA/CD

Assume a broadcast network with a central station. All senders send to the central station, and the central station rebroadcasts all receptions on a different band. In standard CSMA/CD, all senders stop when a collision is detected. In the suggested modified algorithm, exactly one continues to send. A colliding sender can know if it was the first to arrive at the central station. If so, it continues to send, else it stops. The one that continues to send incurs an observable-length erasure burst, and appends a redundant part to its frame to allow filling in the burst erasure.
