Abstract :
In this paper, a novel lower-power multigigabit Viterbi decoder architecture is proposed for 60 GHz wireless personal-area network (WPAN) systems. Since add-compare-select (ACS) computation is the main bottleneck in decoding speed of Viterbi decoders, a balanced add-select-register-compare (BASIC) architecture is put forward to reduce critical path of ACS with low complexity. This work develops an 8-parallel BASIC Viterbi decoder for IEEE 802.15.3c standard to accomplish high-throughput and low-power goals. Based on synthesized results in 0.13 μm CMOS technology, the proposed decoder achieves up to 4 Gb/s throughput with energy efficiency 0.104 nJ/bit at 1.2 V.
