[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.
