Response to the following problem:
A rate ½ convolutional code with d free = 10 is used to encode a data sequence occurring at a rate of 1000 bits/s. The modulation is binary PSK. The DS spread spectrum sequence has a chip rate of 10 MHz.
a. Determine the coding gain.
b. Determine the processing gain.
c. Determine the interference margin assuming an Eb/J0 = 10.
