Table 3.

Four kinds of LDPC Codes are evaluated with 120,000 blocks.

Codewords	$N=7200,M=6000$	$N=9000,M=8000$	$N=9000,M=7200$	$N=16,200,M=13,500$
Bit throughput of using MPI (Mbps)	16.17	15.77	15.34	15.19
Bit throughput of not using MPI (Mbps)	4.08	4.14	4.16	4.78
CPU usage efficiency	88.77%	85.53%	89.16%	90.11%
Number of iterations	5	4	5	3
Frame errors	1045	139	1261	803
FER	8.7e−3	1.16e−3	1.05e−2	6.69e−3

The number of iterations is the average value after 120,000 blocks of codeword measurements. The CPU usage efficiency is the peak value that appears when codewords were evaluated. Take the bit throughput of average value by multiple measurements.
