ABSTRACT:
A method of determining a metric for evaluating an error probability of a data frame includes receiving, at a radio receiving device, the data frame encoded according to a coding method and transmitted through a radio communication channel by a radio transmitting device. The data frame includes a plurality of symbols. The method also includes performing a channel equalization of the data frame received at the radio receiving device to produce a channel equalized data frame, performing a symbol de-mapping of symbols in the channel equalized data frame to produce a de-mapped data frame, obtaining soft bits based on the de-mapped data frame and characteristics of the coding method, and calculating the metric from at least one moment, having an order strictly greater than one, of quantities that characterize an equivalent communication channel for the soft bits.
