MIMO MMSE Estimator

This functionality is available only within the Intel® System Studio suite.
The MIMO MMSE is based on the output of FFT (
y
) and channel estimation (
H
).
The figure below shows the system model used for the MMSE estimation per subcarrier.
According to this figure, the basic equation is
y
=
H
*
x
+
n
where
  • N
    r
     is the number of receive antennas (2, 4, or 8)
  • N
    t
     is the number of transmit antennas (1 or 2)
  • x
     is the data frequency domain symbol

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
