1. Binary communication with polar signaling and raised cosine pulse shape. As discussed in class, the raised cosine pulse has the following characteristic \[ p\left(n T_{b}\right)=\left\{\begin{array}{lr} 1 & n=0 \\ 0 & \text { for notherwise } \end{array}\right. \] When \( \alpha=1 \), the raised cosine pulse looks like Binary Pulse Raised cosine with Roll-Off Factor \( =1 \) a) A received polar signal using raised cosine pulse shaping is shown in the figure below. The sampling instances are shown with the black circles. Eight bits are shown in the signal. From the figure, decipher the 8 bits. b) Find and sketch the power spectral density \( S,(f) \). We covered the necessary equations in class.
