Consider 2 wireless nodes that use CDMA protocol to communicate over a shared Node Data bits Chipping Code S1 0101 S2 10 0011 Use the following scheme: 0 bit: 1 V and 1 bit: -1 V a. What is the channel output at nodes S1 and S2? (2 pts) b. Create a combined waveform (signal) that every single node receives.(3 pts) c. Decode the signal for receiver R1 (original data at S1 must be recovered!)
