Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive a wireless signal represented as a receive matrix. The wireless signal carries one or more information symbols modified through a wireless channel that is represented as a channel matrix. The receiving device may perform QR decomposition on the channel matrix to generate an upper triangular channel matrix. The receiving device may determine a selected demapping technique using the upper triangular channel matrix. The receiving device may perform the selected demapping technique on the receive matrix and the channel matrix. Numerous other aspects are described.
