Channel loss and queuing loss tradeoffs in voice transmission over ATM switching systems

More efficient transmission of coded speech over packet switching systems can be achieved by channel coding. The redundancy introduced by channel coding to recover lost or impaired packets results in an increased traffic and an increased queuing loss. Hence there is a critical tradeoff between channel coding rate and queuing loss. We show that the channel loss rate, the traffic level and congestion rate affect the optimum channel coding rate.
