As mentioned earlier, the fading channel is assumed to be static over the duration of the observation.
Moreover, assuming the channel to be static over the duration of a packet encompassing several OFDM symbols, the time index can be dropped from this point onwards.
For the results shown here, the channel, generated following the specifications in [24], is assumed to remain static over the duration of a packet and vary independently from packet to packet (block fading).
In order to simplify the notation, assuming that the channel is static over the duration of a block (i.e., an OFDM symbol), the frequency response between Tx-antenna i and Rx-antenna j over the N c subcarriers during the kth OFDM symbol can be expressed as h ̄ ij ( k ) = h ̄ 0 ij ( k ) … h ̄ N c − 1 ij ( k ) T. (10).

Best practice
When describing experimental conditions or data, use "static over the duration" to clearly indicate that certain parameters remained constant throughout the experiment to ensure reliable results. This emphasizes the controlled nature of the study.
Common error
Avoid using "static over the duration" when you actually mean that something was dynamic but within a limited range. "Static" implies no change whatsoever, while "dynamic" suggests movement or change, even if constrained.

Ludwig's WRAP-UP
The phrase "static over the duration" is a grammatically correct and usable English phrase that describes something remaining unchanged throughout a specific time period. As confirmed by Ludwig, its usage is most common in scientific contexts but can also be found in news and media. While alternatives like "constant throughout the period" or "stable across the duration" exist, the original phrase is effective for emphasizing consistency. It's important to differentiate "static" from "dynamic" to avoid misrepresenting the nature of the subject being described. Using "static over the duration" effectively conveys a sense of unchanging stability within a defined timeframe.
