Multiple-Input Multiple-Output (MIMO)

MIMO channels, OSTBC, sphere decoding

Communications Toolbox™ provides System objects™ and blocks for modeling generic and LTE-specific MIMO channels, and for encoding, combining, and decoding MIMO signals.

System Objects

comm.MIMOChannelFilter input signal through MIMO multipath fading channel
comm.OSTBCCombinerCombine inputs using orthogonal space-time block code
comm.OSTBCEncoderEncode input using orthogonal space-time block code
comm.SphereDecoderDecode input using sphere decoder

Blocks

MIMO Fading ChannelFilter input signal through MIMO multipath fading channel
OSTBC CombinerCombine inputs for received signals and channel estimate according to orthogonal space-time block code (OSTBC)
OSTBC EncoderEncode input message using orthogonal space-time block code (OSTBC)
Sphere DecoderDecode input using a sphere decoder

Introduction to MIMO Systems

This example shows Multiple-Input-Multiple-Output (MIMO) systems, which use multiple antennas at the transmitter and receiver ends of a wireless communication system.

Spatial Multiplexing

This example shows spatial multiplexing schemes wherein the data stream is subdivided into independent sub-streams, one for each transmit antenna employed.

Adaptive MIMO System with OSTBC

This model shows an adaptive orthogonal space-time block code (OSTBC) transceiver system over a multiple-input multiple-output (MIMO) channel.
