a. Use the given code to convert 'bit_stream' that is generated in Part I c. to a, and by, and plot the constellation. b. Convert a, and b, to delta functions and plot them into one figure, using time interval (0.02. 0.04). See example below. a, and b, as narrow polar pulses (almost delta functions) Amplitude (Volts) 8.02 0.022 0.024 0.025 0.028 0.03 0.032 0.034 0.036 0.036 0.04 t(seconds) d. Generate a(t) and b(t) by convolving a raised-cosine pulse (code for the pulse is provided). Sample at the middle of each pulse. Plot a(t), b(t), and the samples between t = 0.02s~0.04s. See example below. (Hint: What is the pulse rate? 16-QAM has 2 channels, where each channel encodes 2 bits per pulse). Since Matlab only does discrete calculation, assuming 99 values are used per pulse.
