Patent ID: 10644778

Abstract:
Per given time instance, K samples b are acquired from a signal r, which is based at least on K transmitted symbols x and a transfer matrix H of a communication channel, and a linear detection matrix A of a size K×K is acquired, which is based at least on the transfer matrix H (S101). For the K samples b and the linear detection matrix A, at most K(K−1) tentative parameters b{tilde over ( )} and at most K(K−1) tentative parameters A{tilde over ( )} are iteratively calculated (S102). It is checked whether or not the tentative parameters b{tilde over ( )} and A{tilde over ( )} have converged (S103). If b{tilde over ( )} and A{tilde over ( )} have converged, K estimation values x{circumflex over ( )} are decided for the K transmitted symbols x based on b{tilde over ( )} and A{tilde over ( )} (S104). If b{tilde over ( )} and A{tilde over ( )} have not converged, it is returned to the iteratively calculating b{tilde over ( )} and A{tilde over ( )} for the K samples b.
