Therefore, the DDFE structure behaves as a linear equalizer fed by the training sequence at the first iteration.
Since the data is transmitted all the time, these schemes allow efficient bandwidth efficiency but may suffer from the interference caused by the training sequence.
M is assumed to be sufficiently large and so that all the statistical properties of the source are captured by the training sequence.

If PU is sensed by TSU, the training sequence will not be transmitted to RSU.
In the current WLAN, the receivers estimate the channels by receiving the training sequence in the PLCP preamble of each frame.
Moreover, by multiplexing the training sequence before precoder, training symbols can be exploited in both the initialization and iteration phases of the iterative channel estimation process.
Moreover, it is shown that by scrambling the training sequence and the message sequence separately with two independent scrambling sequences, both information privacy and system performance can be further improved.
(3) The data sender can also obtain CSI by estimating the training sequence included in MU-CTSs, which enables it to receive B-ACKs in parallel, therefore further reducing temporal overheads.
This can be interpreted by the fact that when, the acquisition is frequent and the network will be overloaded by the training sequences.
All sequences in the General Training Set are formed by the training sequences that cannot be predicted by the sequence alignment method.
By means of the training sequence, the maximum likelihood (ML) estimator, which asymptotically achieves the CRLB, is proposed in [17].
Write better and faster with AI suggestions while staying true to your unique style.
Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
