SOLUTION:
Let X be the number of stations in a certain network. In this case it is 250 stations.
Then the numbers of sequences in a Walsh Table required (let us represent it as Y) should be ( Y = 2n ).
We have to take the n value such that Y is closest to X and greater than X.
So we should take n = 8 which gives Y = 28 = 256.
Hence the answer is Y=256.
NOTE: From these sequences we can use 250 of the sequences as chips for the network to suffice the purpose.

A company named RT&T has a network of n switching stations connected by m high-speed communication links. Each customer’s phone is directly connected to one station in his or her area. The engineers of RT&T have developed a prototype video-phone system that allows two customers to see eachother during a phone call. In order to have acceptable image quality, however, the number of links used to transmit video signals between the two parties cannot exceed 4. Suppose that RT&T network...

(Station closing) Suppose you are in charge of a rail network connecting a large number of towns. Recently, several cases of a contagious disease have been reported in a town A. Your goal is to close down certain railway stations to prevent the disease from spreading to your hometown B. No trains can pass through a closed station. To minimize expense, you want to close down as few stations as possible. However, you cannot close the station A, as this...

Three radar stations, operating independently, are set to detect any aircraft flying through a certain area. Each station has a probability of 0.85 of detecting a plane in its area. If an aircraft enters the area, a. what is the probability that it is detected by all three radar stations? b. what is the probability that the plane is not detected by any of the radar stations? c. what is the probability that the plane is detected by only one...

Alice and Bob are experimenting with CDMA using a w2 Walsh table. Alice uses the code [+1, -1] and Bob uses the code [+1, +1]. Assume that they simultaneously send a hexadecimal digit to each other. Alice sends (8)16 and Bob sends (C) 16. Show how they can detect what the other person has sent in details. (Note: Show your work in clear and neat steps.)
