… the problem of optimal training signal design for frequency-selective block-fading channel
estimation in … This section investigates training signal design for channel estimation based on …

… In this section, we extend the optimal training approach to the case of multiple LS channel
estimates. If there are multiple training periods available within the channel coherency time, it …

… training sequences from the AP) and AP beam training (using uplink training sequences

… III, we introduce LS channel estimation; the analysis of the LS channel estimator is derived
in Section IV, through which we derive an optimal training strategy; Section V presents …

… We will call these special types of training sequences optimum channel independent (OCI)
sequences. From the previous discussion, we conclude that the DFT of an OCI sequence …

auto correlation and zero cross correlation to designing a single training … suboptimal training …

… Besides, transmitting the estimated channel will suffer from further distortions. In this work,
we propose a novel training based channel estimation scheme, where the overall channel …
