TRANSMITTING SET, RECEIVING SET AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To improve a throughput by lessening the number of re-transmitting until getting error-free by improving a receiving level and error-correcting capability. SOLUTION: A receiving set 200 performs the separation of systematic bits and parity bits each other from a received packet (ST406), performs symbol- composition of the systematic-bits in the separated re-transmitted unit at this time and the systematic-bits acquired in the re-transmitted units until the last time (ST407); and performs likelihood-composition the separated parity-bits and each parity-bits acquired in the re-transmitted units until the last time, and decodes with error-correcting the systematic-bits of post-symbol-composition using the parity-bits of post-likelihood-composition as the examination bit (ST410).
