2 (4.24-mm² cell area or 556K equivalent and gates). In postlayout simulations, this decoder achieves an average information throughput of 5.71 Gb/s and an energy consumption of 65.8 pJ per information bit at a signal-to-noise ratio of 5.5 dB. Our results show a 21% reduction in area, a 0.6-dB improvement in coding gain, and an energy efficiency improvement of 19% over the comparable bit-serial MS decoder architecture. We also demonstrate 3-bit implementations, in which the coding gain is traded off for further improvements in throughput, area, and energy efficiency.">
