* Consider 3 wireless nodes that use CDMA protocol to communicate over a shared medium: Node SI S2 S3 Data bits Chipping Code 0101 0011 10 use the fol llowing scheme: 0 bit-> + I Vand I bit -> -I V What is the channel output at every node? that every single node red Decode the signal for receiver I (original data at SI must be recovered!)
