Table 1 Computational complexity of BLMMSE estimator, KFB estimator, and TPE-based estimator
From: Channel estimation for spatially/temporally correlated massive MIMO systems with one-bit ADCs
Channel estimator | Computational complexity |
|---|---|
BLMMSE estimator | \(\mathcal {O}(M^{3}\tau ^{3})\) |
KFB estimator | \(\mathcal {O}(M^{3}\tau ^{3})\) |
TPE-based estimator | \(\mathcal {O}(LM^{2}\tau ^{2})\) |
