Single Carrier Frequency Division Multiple Access (SC-FDMA) is adopted as uplink multiple access scheme in 3G Long-Term Evolution (LTE). Combining SC-FDMA with MIMO (Multiple-Input Multiple-Output) can increase capacity and throughput but detection technique is required at the Base Station (BS). Interference Cancellation (IC) based on Cyclic Redundancy Check (CRC) is a conventional detection algorithm. In this paper, the authors divide IC into useful IC and useless IC. Simulation results indicate that CRC-based IC algorithm performs too many useless ICs, which increases the complexity.
