Abstract :
We present a modified stochastic LDPC decoding algorithm suitable for implementation at 100-Gb/s and above. The stochastic decoding is invented for low-precision digital circuits, and as such is suitable for beyond 100-Gb/s implementation to avoid the problem of nonexistence of high-precision analog-to-digital converters operating at those speeds.
