Rate matching device, radio transmitting device, radio receiving device and rate matching method

摘要

The rate matching device which can improve the bit error rate quality on data receiving end is offered. The rate matching section as a rate matching device (106), N (N integer of 1 or more) from the 1st encoding block where is suitable to symbol, N+K (as for K integer of 1 or more) the 2nd encoding block where is suitable to symbol is formed. The rate matching section (106) in, the divided object bit group extraction section (122), from 1st encoding block, the 1st bit group where N is suitable to either of symbols is extracted. The divided section (124), the 1st bit group which is extracted, L (L integer below K+1 of 2 or more) L where is suitable to symbol dividing into the divided bit group, you obtain 2nd encoding block.
