[10GBT] Simulated Performance of RS (2048,1723) LDPC code


We have just completed Sum-Product Algorithm simulations of the RS
(2048,1723) LDPC code at an SNR of 19.9dB with the PAM8 constellation. The
simulations were conducted both in 12-bit fixed point arithmetic using
4096-word lookup tables and in floating point arithmetic.

For 7,302,369,000 blocks at an SNR of 19.9dB, corresponding to 20.06
trillion information bits and 22.43 trillion coded bits, there were 18 bit
errors using fixed point arithmetic (for a mean BER estimate of 8.9E-13) and
0 bit errors using floating point arithmetic.
