Simulate the numerical BER of Unipolar NRZ in AWGN channels

After reading the sheets given from the supervisor, we clearly understand some concepts of the noise systems and some parameters such as unipolar, bipolar and bits error rate(BER) etc. In matlab, the simulation of the unipolar NRZ is shown below,

As the project required, we should simulate another AWGN channel which relate to Bipolar. The latest result will come out at next blog.
