Abstract

A method of data transfer between a transmitter and a receiver over a communications link achieves maximum throughput by dynamically adapting a coding rate, and specifically an error correction encoder, as a function of a measured reverse channel signal parameter. The method comprises the steps of transmitting a signal from the transmitter to the receiver, the receiver receiving and measuring the signal to noise ratio of the transmitted signal. The receiver determines an appropriate code rate and encoding technique as a function of the measured signal to noise ratio and transmits an encoding identifier of the determined encoder to the transmitter. The transmitter encodes its data according to the encoding identifier and transmits the encoded message to the receiver. The receiver receives the encoded message and decodes the message according to the determined code rate and encoding technique.
