METHOD, APPARATUS, AND SYSTEM FOR MEASURING A MIMO CHANNEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18482874 titled 'METHOD, APPARATUS, AND SYSTEM FOR MEASURING A MIMO CHANNEL
Simplified Explanation
According to the present disclosure, this patent application describes methods and devices for estimating a high-dimensional MIMO (Multiple-Input Multiple-Output) channel. The MIMO channel is expressed as a flow function, which represents the change from an input state to an output state. This approach is similar to solving fluid dynamic problems.
Key points of the patent/innovation:
- The MIMO channel is represented as a flow function, allowing for a more accurate estimation.
- Linearization is not used to estimate all coefficients of the MIMO channel matrix.
- The receiver determines the rank of the MIMO channel by detecting leading modes in a subspace of the entire MIMO channel matrix.
Potential applications of this technology:
- Wireless communication systems: This technology can be applied to improve the estimation of MIMO channels in wireless communication systems, leading to better signal quality and higher data rates.
- Internet of Things (IoT): MIMO technology is crucial for IoT devices that rely on wireless communication. This innovation can enhance the performance and reliability of IoT networks.
- Autonomous vehicles: MIMO channels play a vital role in vehicle-to-vehicle communication systems. By accurately estimating the MIMO channel, this technology can improve the safety and efficiency of autonomous vehicles.
Problems solved by this technology:
- Inaccurate MIMO channel estimation: Traditional methods using linearization may not provide accurate estimates of the MIMO channel, leading to degraded performance in wireless communication systems.
- High-dimensional MIMO channels: Estimating high-dimensional MIMO channels can be challenging due to the large number of coefficients involved. This technology provides a more efficient and accurate approach to handle such channels.
Benefits of this technology:
- Improved signal quality: Accurate estimation of the MIMO channel allows for better signal quality, reducing errors and improving the overall performance of wireless communication systems.

Original Abstract Submitted
According to the present disclosure, there are provided methods and devices for estimating a high-dimensional MIMO channel by expressing the MIMO channel in the form of a flow function to determine a change from an input state to an output state. This may be considered similar to a manner in which fluid dynamic problems are solved. Instead of using linearization to estimate all of the coefficients of a matrix representing a MIMO channel, a receiver may determine the MIMO channel rank by detecting leading modes in a subspace of the entire MIMO channel matrix.
