... thus conflicting metrics that must be balanced. There has been extensive research on improv- ing the transmission power efficiency with constraints on nonlinear distortions in single-input single-output ... perspective, the joint MRC and clipping mitigation method has lower complexity than PWLS and optimal clipping schemes. In addition, it can achieve better coding gain, which will...
