==DEVICES AND METHODS FOR RECURSIVE BLOCK PRECODING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240030969 titled 'DEVICES AND METHODS FOR RECURSIVE BLOCK PRECODING

==Simplified Explanation==

The abstract describes a precoder for sending information symbols to multiple users. The precoder includes a user ordering and grouping unit that groups users based on quality of service indicators and modulation and coding parameters. It divides a predefined upper triangular precoding matrix and the vector of information symbols into sub-matrices and sub-vectors, respectively, based on an arbitrary order of the quality of service indicators. 

The precoder also includes a precoding unit that determines a perturbation vector to minimize transmit power. The perturbation vector consists of perturbation sub-vectors, each corresponding to a sub-vector of information symbols. The precoding unit uses a recursive search algorithm to estimate each perturbation sub-vector.

* The patent describes a precoder that optimizes the transmission of information symbols to multiple users.
* The user ordering and grouping unit groups users based on quality of service indicators and modulation and coding parameters.
* The precoder divides the precoding matrix and information symbol vector into sub-matrices and sub-vectors, respectively, based on the order of quality of service indicators.
* The precoding unit determines a perturbation vector to minimize transmit power.
* The perturbation vector consists of perturbation sub-vectors, each corresponding to a sub-vector of information symbols.
* The precoding unit uses a recursive search algorithm to estimate each perturbation sub-vector.

Potential applications of this technology:
