Abstract:
1. A method for correcting errors in data conveyed by a communications network comprising one or more transmitters and one or more receivers, wherein the method comprises: receiving one or more packets of data each including data representing a plurality of parameters; checking consistency of data representing two or more specified parameters that are included in the one or more packets of data using correlation characteristics of the two or more specified parameters, wherein the consistency is checked using a process that is independent of error-correction codes, and wherein the specified parameters are communication control parameters or application parameters; if the check indicates the data are not consistent, selecting a parameter from the two or more specified parameters that is represented by data having the highest probability of corruption according to an error model that describes probabilities of data corruption in packets of data during transmission of the packets; and modifying the data representing the selected parameter such that the data representing the two or more specified parameters are consistent according to the check.
