Filter input signal through MIMO multipath fading channel
Communications Toolbox / Channels
Communications Toolbox / MIMO
The MIMO Fading Channel block filters an input signal using a multi-input/multi-output (MIMO) multipath fading channel. This block models both Rayleigh and Rician fading and employs the Kronecker model for modeling the spatial correlation between the links. For processing details, see the Algorithms section.
The availability and dimensions of input and output port signals depends on:
The Antenna selection parameter setting on the Main tab
The Initial time source parameter setting on the Realization tab
The Output channel path gains selection on the Realization tab
Antenna Selection Parameter | Signal Input (in) | Transmit Selection Input (Tx Sel) | Receive Selection Input (Rx Sel) | Initial Time Offset Input (Init Time) | Signal Output (Out1) | Optional Channel Gain Output (Gain) |
---|---|---|---|---|---|---|
Off | NS-by-NT | N/A | N/A | nonnegative scalar | NS-by-NR | NS-by-NP-by-NT-by-NR |
Tx | NS-by-NST | 1-by-NT | N/A | NS-by-NR | ||
Rx | NS-by-NT | N/A | 1-by-NR | NS-by-NSR | ||
Tx and Rx | NS-by-NST | 1-by-NT | 1-by-NR | NS-by-NSR |
NS represents the number of samples in the input signal.
NT represents the number of transmit antennas, as determined by:
Transmit spatial correlation when Specify spatial correlation is set to Separate Tx Rx
Number of transmit antennas when Specify spatial correlation is set to None
or
Combined
NR represents the number of receive antennas, as determined by:
Receive spatial correlation when Specify spatial correlation is set to Separate Tx Rx
Number of receive antennas when Specify spatial correlation is set to None
Combined spatial correlation and Number of transmit antennas when Specify spatial correlation is set to Combined
NP represents the number of channel paths, as determined by the Discrete path delays (s) or Average path gains (dB).
NST represents the number of selected transmit
antennas, as determined by the number of elements set to 1
in the vector
provided to the Tx Sel input
port.
NSR represents the number of selected receive
antennas, as determined by the number of elements set to 1
in the vector
provided to the Rx Sel input
port.
