Question

There are four stations communicating using CDMA (code division multiple access). The code assigned to each station is as follow: A: (+1+1+1+1) B: (+1 +1 -1 -1) C: (+1-1-1+1) D: (+1-1+1-1) Given the 4-bit messages sent by A, B, C, D are (0101)$_{2}$, (1101)$_{2}$, (1001)$_{2}$, (0011)$_{2}$, respectively. Derive the overall signal delivered in the channel. Show the steps you derive the answer.

Step 1

For A: (0101)2 becomes (+1-1+1-1) For B: (1101)2 becomes (+1+1-1-1) For C: (1001)2 becomes (+1-1-1+1) For D: (0011)2 becomes (+1+1+1+1) Show more…
