How do I change the amplitude of a signal based on uniform random distribution? Not sure how to proceed.

Hi Prashant,
In your question, transmitter output is two level NRZ signal. For generating the data bits based on uniform random distribution, you may use the follwing command:
bits = (randi([0 1],1,100)).'
The above command will generate the bit sequence of 1s and 0s with random distribution of equal probabilty of 1 and 0.
To convert these data bits into NRZ line coding please refer to the following file exchange :
This file contains a function unrz which is for unipolar NRZ signal. For your question you can modify the code. Under else condition, assign the x value as -1.
