"I have a hard time adding some of my own comment in the paper as mentioned in my rough draft because I am unfamiliar with the topic.
For reasons of simplicity and to maintain the focus of the present paper, as mentioned above, only two of the most practical and popular MIMO techniques are considered here, MMSE precoding and V-BLAST detection.
In this paper, as mentioned earlier, the combination of the best known techniques for a multiple-antenna two-way relay system consisting of two sources of multiple antennas and multiple relays of single antenna is considered.
Later, in a writing response assignment, Wes noted that his lack of knowledge on the topic and lack of skill with citation practices prevented him from including his voice in an effective way: "I have a hard time adding some of my own comment in the paper as mentioned in my rough draft because I am unfamiliar with the topic.

It also became apparent that the introduction of the new system not only impacted on individuals, but also had an effect on paper records (which were, as mentioned above, still used in parallel).
By our approaches, we obtain various types of URAs including the filled URAs which can be constructed by existing methods and the sparse URAs which have never been constructed and mentioned by existing papers as far as we know.
As mentioned in Paper I, this can be explained by the offsets of the measurement points from the crack plane, and, therefore, gets smaller for smaller Δh.
