Summary<br />
• The MU-<strong>MIMO</strong> with receive beamform<strong>in</strong>g comb<strong>in</strong>ed with<br />
multiuser is still an <strong>in</strong>terest<strong>in</strong>g alternative MU-<strong>MIMO</strong> subject to<br />
feedback channel errors.<br />
• Imperfect CST at the receiver (CRI-R) will cause serious sum-rate<br />
performance degradation and cause the sum-rate floor.<br />
– Sum rate capacity will no longer l<strong>in</strong>early <strong>in</strong>crease with<br />
SNR <strong>in</strong> decibel and be bounded.
