Abstract:
1. A communication system, comprising: a transmitter, including a receiver, including a combination of data bits retransmitted from a part or all of the plurality of transmission antennas at the same time is the same as a combination of data bits having already been transmitted from a part or all of the plurality of transmission antennas at the same time; the combination of data bits retransmitted from a part or all of the plurality of transmission antennas at the same time includes at least one of data bits which are not object of the retransmission; and the retransmission combination processing is performed with the product or the sum of logarithm likelihood of the probability of specific combinations of grouped data bits that are the object of the retransmission and grouped data bits that are not the object of the retransmission wherein the logarithm likelihood of the probability of the specific combinations of grouped data bits used for combination processing meet optimized value criteria.
