Hypothesis: 3. The designed PHY layer will meet the requirements of the IEEE 802.11ay standard for wireless communication.
To test this hypothesis, we conducted a thorough analysis of the IEEE 802.11ay standard and designed the PHY layer to meet all of the requirements outlined in the standard. We then conducted simulations and experiments to verify that the designed PHY layer met these requirements, providing support for this hypothesis.
Our analysis and simulations showed that the designed PHY layer met all of the requirements of the IEEE 802.11ay standard, including those related to modulation and coding schemes, channel bandwidth, channel access methods, and spatial streams. Furthermore, we observed that the designed PHY layer provided better performance in terms of data rate, range, and energy efficiency compared to existing PHY layers in the IEEE 802.11 standard.
These results demonstrate that the designed PHY layer is capable of meeting the requirements of the IEEE 802.11ay standard while providing improved performance compared to existing PHY layers. Overall, the results of our analysis and simulations support the hypothesis that the designed PHY layer will meet the requirements of the IEEE 802.11ay standard for wireless communication.

Literature Review:
To design and evaluate the IEEE 802.11ay PHY layer, we used MATLAB, a powerful numerical computing software that allows us to simulate and analyze wireless communication systems.
First, we used MATLAB to develop a model of the IEEE 802.11ay PHY layer based on the standard's specifications. This involved implementing the various signal processing algorithms and modulation schemes used in the PHY layer, such as channel encoding, modulation and demodulation, and error correction coding. We also used MATLAB to model the wireless channel and simulate the transmission of signals through the channel.
Next, we conducted a series of simulations to evaluate the performance of the designed PHY layer in terms of data rate, range, and energy efficiency. For example, we simulated the transmission of data packets over different distances and under varying channel conditions, such as with and without line-of-sight (LOS) between the transmitter and receiver. We also varied the transmission power and receiver sensitivity to evaluate the energy efficiency of the designed PHY layer.
Finally, we compared the performance of the designed PHY layer with existing PHY layers in the IEEE 802.11 standard using MATLAB. We implemented the existing PHY layers in MATLAB and conducted similar simulations to evaluate their performance in terms of data rate, range, and energy efficiency. We then compared the results of these simulations with those obtained for the designed PHY layer to determine its relative performance.
Overall, MATLAB provided a powerful tool for designing and evaluating the IEEE 802.11ay PHY layer. Its simulation capabilities allowed us to test the performance of the PHY layer under a wide range of conditions and compare it with existing standards, providing valuable insights into its strengths and weaknesses.

This code generates a random data packet, prepends a sequence of known bits to it for channel estimation, and then transmits it over a wireless channel using the designed IEEE 802.11ay PHY layer. The signal is received, demodulated, and the bit error rate (BER) is calculated for each packet. Finally, the BER vs. packet number is plotted to visualize the performance of the PHY layer. This is just a simple example and there are many other simulation scenarios and metrics that could be evaluated using MATLAB.
