Abstract
According to a method and apparatus taught herein, a network node includes a receiver circuit that determines soft values for received packets corresponding to the information bit groups associated with network coding operations, where the soft values are determined for each information bit group based on joint probabilities of the information bits within the information bit group. For example, first soft values are determined for the information bit groups in a first (received) constituent packet and second soft values are likewise determined for the information bit groups in a network-coded (received) packet that depends on the first constituent packet and a second constituent packet. Third soft values are generated for the information bit groups of the second constituent packet based on jointly evaluating the first and second soft values.
