CDMA. 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. Show the following:                    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. Sender 1: ___________________________________________ 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 the sender 1, is able to recover the received data.            

Which the following cryptosystem is a public-key cryptosystem?

Subnet division.An institution is given the following IP address block by its ISP: 18.14.8.0/21. Divide this IP address block into smaller subnets to fit for three departments, which require 1000, 200, and 200 IP addresses. To receive full credit, you must: 1. Start from the 1000-host subnet. 2. Make sure the three subnets are continuous. 3. Show your work in “a.”, and fill the final answer. Also, consider x.x.x.0 and x.x.x.255 as valid IPs.           a.   Show your work                    b.   (4 pts) For the 1000-host department: Subnet address (x.x.x.x/x): _______________________________ Subnet mask (x.x.x.x): ___________________________________ First Host IP: ____________________________________________ Last Host IP: ____________________________________________                    c.   (4 pts) For the first 200-host department: Subnet address (x.x.x.x/x) ________________________________ Subnet mask (x.x.x.x): ___________________________________ First Host IP: ____________________________________________ Last Host IP: ____________________________________________             d.   (4 pts) For the second 200-host department: Subnet address (x.x.x.x/x): _______________________________ Subnet mask (x.x.x.x): __________________________________ First Host IP: __________________________________________ Last Host IP: ___________________________________________
