METHODS AND SYSTEMS FOR EXTRACTING A JOINT PROBABILITY FROM A MAP DECISION DEVICE AND PROCESSING A SIGNAL USING THE JOINT PROBABILITY INFORMATION

摘要

Methods and devices for extracting a joint probability from a MAP decision device are provided. Probability information associated with a first symbol and a second symbol is obtained from the MAP decision device. A joint probability of the first symbol and the second symbol is determined from the probability information associated with the first symbol and the second symbol. Methods and devices for processing a signal containing information associated with a plurality of transmitted bits using the generated joint probability information are also provided. The MAP decision device in various embodiments is a demodulator or a decoder.
