Hi, Wang, Almost always the step after the channel equalizer is a requantization to fewer bits (typically 4 or 8). You will want to ensure that the data is getting equalized to a level that makes optimal use of the output bits. What constitutes "optimal use" is a rather complicated topic, but generally it's good to have an output RMS between 2 and 3 for Fix_4_0 output types or 15 to 30 for Fix_8_0 output types.
I'm sure there are plenty of other things to pay attention to as well, but this is one area that is often neglected.
