Abstract
This paper presents a turbo decoder chip supporting all 188 block sizes in 3GPP LTE standard. The design allows 1, 2, 4, or 8 SISO decoders to concurrently process each block size, and the number of iteration can be adjusted. Moreover, a threestage network is utilized to connect multiple memory modules and multiple SISO decoders. After fabricated in 90nm process, the 2.1mm2 chip can achieve 129Mb/s with 219mW for the 6144-bit block after 8 iterations.
