Low complexity ordered successive interference cancelation detection algorithm for uplink MIMO SC‐FDMA system

In mobile communication, the most exploratory technology of fifth generation is massive multiple input output (MIMO). The minimum mean square error and zero forcing based linear detectors are used in multiuser detection for MIMO single-carrier frequency division access (SC-FDMA). When received signal detected regularization sequence joined equalization spectral null amplification, these schemes experience an performance assesses inversion a matrix computation that grows into complexity. Ordered successive interference cancelation (OSIC) considered SC-FDMA, which uses posteriori information to eradicate problems realistic environment. To cancel interference, sorting preferred on signal-to-noise ratio log-likelihood ratio. distinctiveness methodology predict symbol with lowest probability. proposed work compared existing methods, simulation results prove defined algorithm outperforms conventional methods accomplishes better lower complication.
