Consider the CDMA technique and assume that users A and B have spreading codes 01010101 and 01011010, respectively. Denote bit 0 as -1 and bit 1 as +1. (a) How can one determine if these two spreading codes are orthogonal? (b) What is the compound signal content if A sends a data bit 0 and B sends a data bit 1? (c) What data bit is transmitted by users A and B, respectively, if the compound signal content is (0, 0, 0, 0, -2, 2, -2, 2)? (d) How can a user know that the received signal content does not contain relevant data bits to

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
