Fig. 2From: Power imbalance induced BER performance loss under limited-feedback CoMP techniquesBit error rate as a function of \(\bar {\gamma }_{1}\) when σ 0=0 dB and σ 0=6 dB. Dashed curves refer to the analytical asymptotic BER results; solid curves refer to the approximate BER results; and markers refer to the simulated BER resultsBack to article page
