Algorithm 1: Extraction of Spatial Information Based on MPCs
	Input: $Q$ data files, each containing $K$ sample points of I/Q data from both moving and stationary antennas at $q$-$\mathrm{t}\mathrm{h} (1\le q\le Q)$ different angular position.
	Output: A $.mat$ file with spatial angles $Degrees$ and corresponding power values $Power$.
1.	for each data file $q=1 to Q$ do
2.		Read the file to extract the angular position ${\theta }_0\left(k\right)$ and $2K$ corresponding I/Q samples from both the moving antenna reception ${\tilde{h}}_1\left(k\right)$ and the stationary antenna reception ${\tilde{h}}_2\left(k\right)$.
3.		Store ${\theta }_0\left(k\right)$ as the $key$ and ${\tilde{h}}_1\left(k\right)$, ${\tilde{h}}_2\left(k\right)$ as the $value$ in the mapping table $d\left\{key\right\}$.
4.	end
5.	for each $key$ in $d$ do
6.		Extract the data ${\tilde{h}}_1\left(k\right)$ and ${\tilde{h}}_2\left(k\right)$ for $K$ sample points, respectively.
7.		Compute the ratio $h_r\left(k\right)$ of ${\tilde{h}}_1\left(k\right)$ to ${\tilde{h}}_2\left(k\right)$ and store the result in the updated mapping table $d_{updte}\left\{key\right\}$, with the calculation of $h_r\left(k\right)$ performed as follows:
	$h_r\left(k\right)={\displaystyle \frac{1}{K}}\sum _{k=1}^K{\displaystyle \frac{{\tilde{h}}_1\left(k\right)}{{\tilde{h}}_2\left(k\right)}}$.
8.	end
9.	for $cos \theta =-1 to 1$, with a step size of $0.01$ do
10.		for each $key$ in $d_{updte}$ do
11.		Calculate the received power $P\left(\theta \right)$ at spatial angle $\theta$ based on Equation (16).
12.		end
13.		Store the current angle $\theta$ in the array $Degrees$, and the corresponding power $P\left(\theta \right)$ in the array $Power$.
14.	end
15.	Save the arrays $Degrees$ and $Power$ as a $.mat$ file for further analysis.
