Application Number: JP,2024-091375
Category (FI): H04L27/26,111,H04B7/0413
Stage: PROBLEM TO BE SOLVED: To provide, generally, data communication, and more specifically, techniques for increasing the wireless transmission efficiency using a layered construction of arbitrary unitary matrices.SOLUTION: A method includes: generating, via a first processor of a first compute device, symbols based on incoming data; and decomposing a unitary matrix of size NN by 1) applying a permutation to each symbol using a permutation matrix, to produce permuted symbols, and 2) transforming each symbol using at least one primitive transformation matrix of size MM, M being less than or equal to N, to produce transformed symbols. The method also includes sending a signal representing the transformed symbols to a plurality of transmitters for transmission of a signal representing the transformed symbols to a plurality of receivers. A signal representing the unitary matrix is sent to a second compute device for transmission of the unitary matrix to the receivers for recovery of the plurality of symbols at the plurality of receivers.SELECTED DRAWING: Figure 2 (Grant)
