Answer Happy

the system nominally use -bit el represent a binars and -1 to represent a binary 0; however, after passing The DMA system is using 4-bit orthogonal codes and synchronous timing, with a chip rate of 2 Mchips/sec, through a transmitter, wireless channel and receiver the amplitudes will be changed. signals from multiple users. User X has code 0101 and User Y has code 1001. At the output of the receiver, the following time sequence of values is obtained, representing the summed -0. 1.5 os ar 0.3 -1.5 2.5 -1.3.1.5 0.3 -1.3 2.5 1.4 -1.4 0.4 -0.4 (a) How many data bits does the sequence above represent, for each user? (b) Find the data sent by cach user. (C) Assuming both transmitted with the same amplitude, which user is probably closer to the receiver Prahlen
