A Direct Sequence Spread Spectrum system receives a 100 Mbps digital signal at its input and transmits a spread signal at 800 Mbps. The received spread signal has an SNR of -3dB.

1. What is the Gain of that system?

2. Write down any chip of your own that satisfies the condition stated above.

3. For the data bit stream 0 0 1 1 0 0 1 0 0 1, what is the corresponding spread bit stream, using your chosen chip above?

5. Consider a 4 channel CDM system with the following CHIPS: A: -1 -1 -1 1 B: -1 -1 1 -1 C: -1 1 -1 -1 D: -1 1 1 1 a) Show that each one of those chips is orthogonal to all of the others. b) If the CDM signal 1 -1 -3 1 is received, by all receivers, what will be the conclusion of each one?
