“…In [20,21], cross-entropy (CE) method is employed to search for the near-optimal position of the training symbol that minimizes the channel estimate MSE. The scheme in [20,21] works well and provides similar results as the proposed AMCMC algorithm; however, the convergence of the CE algorithm is inferior to that of the AMCMC algorithm. AMCMC converges faster than the CE scheme due to some restrictions imposed on the generated samples of subcarrier sets.…”

“…Thus we resort to the estimator in [4] for estimation of I / Q imbalance parameters only. In [21], it is demonstrated that, although I / Q imbalance is effectively estimated and compensated for, channel estimation using special pilot pattern is very poor, which in turn cause severe deterioration in bit error rate (BER) performance. Interested readers are referred to [4] for more details about I / Q imbalance parameter estimation and compensation algorithm.…”

“…For example, replacing the direct conversion architecture (DCA) with a superheterodyne configuration scheme with low cost and lower power utilization in silicon compared to the super heterodyne can lead to an imbalance of Inphase and Quadrature (IQ). IQ imbalance can be described as the difference between the gain, phase, and even frequency response of each orthogonal branch of communication systems [4,5].…”
