A transmitter uses an adaptive forward error control scheme that includes redundant packets to reduce packet error rate at a receiver. The receiver analyzes the received packet error rate before correction to determine an optimal level of redundancy required to respect a maximum tolerated packet error rate after correction, and communicates this determined optimal level to the transmitter for cont...
