Reverse Rate Matching for Low-Power LTE-Advanced Turbo Decoders

In this paper, a reverse rate matching method is presented for LTE-Advanced turbo decoders. In LTE-Advanced systems, the turbo codes are highly punctured to achieve high data rate when the channel is reliable. In that case, since only a small part of the input frame memory contains meaningful data, accessing all entries of the memory is redundant. To reduce the meaningless accesses, the proposed r...
