In Wireless slides, Code Division Multiple Access (CDMA) is introduced on slides 20 & 21. Please show the procedures that receiver 2, who has the same code as sender 2, can recover the encoded data. Assume sender 1 has the code -1,+1,-1,-1,+1,-1,-1, +1 , and sender 2 has the code +1,-1,+1, -1, +1,+1,-1,+1. Assume sender 1 sends 2 bits +1, -1, and sender 2 sends 2 bits -1, +1. a. (4 pts) What is the encoded data sent by sender 1 and sender 2? Fill the blank, and then show your work in the following blank. i. Sender 1: ___________________________________________ ii. Sender 2: ___________________________________________ b. (4 pts) What is the “channel output”, i.e., the data that is sent on the channel that combines both sender 1 and sender 2’s data. Fill the blank and show your work below. Channel output: ___________________________________________ c. (5 pts) Show that receiver 1, who has the same code as sender 1, can recover the received data.
