RE: [10GBASE-T] question about the complexity reduction of MIMO
Xiaopeng
I would claim the maximum is a 16x reduction. So, a practical realization is in the range 4x to 16x. Our approach is somewhere around 7x. Note, a MIMO realization is not unique. But, this is not a concern for the study group.

Subject: [10GBASE-T] question about the complexity reduction of MIMO
Bill,
I have a quick question about MIMO. In your presentation, you stated that
the MIMO architecture can help to reduce the DSP complexity from 10 to 1.5.
For a 4x4 MIMO system, the maximum complexity reduction is 4 times if I am
not wrong. In this extreme case, a one-channel DSP engine can be reused
for 4 channels without any modification. However even in such a case, the
DSP complexity is still 2.5.
