The authors propose a new reception scheme based on the successive interference cancellation (SIC) approach by jointly performing zero forcing (ZF) and minimum mean squared error (MMSE) according to a defined threshold. A complexity analysis is provided although upper and lower complexity bounds are also derived. A detailed performance evaluation is presented, which explicitly indicates the usefulness of the proposed switching method across the conventional ZF–SIC and MMSE–SIC in terms of computational savings and/or error resilience. An alternative switching threshold which is based on the ergodic capacity is also presented, in case of capacity‐driven applications.
