A CDMA system is using 4-bit orthogonal codes and synchronous timing, with a chip rate! The system nominally uses +1V to represent a binary 1 and - IV to represent a binary 0; however, after passing through a transmitter, wireless channel and receiver the amplitudes will be changed. At the output of the receiver, the following time sequence of values is obtained, representing the summed signals from multiple users. User X has code 0101 and User Y has code 1001. 0.3 -1.4 -0.4 -1.3 .1.3 -1.5 -1.5 2.5 1.4 0.4 2.5 0.3 -0.5 1.5 -0.7 -0.3 (a) How many data bits does the sequence above represent, for each user? (b) Find the data sent by each user. (c) Assuming both transmitted with the same amplitude, which user is probably closer to the receiver?
