A DSS-CDMA system has four users A, B, C, and D, with chip codes [+1, +1, +1, +1], [+1, -1, +1, -1], [+1, -1, -1, +1], and [+1, +1, -1, -1], respectively. (a) Find out the data bits (if any) transmitted by the users A and B for the following sequence received at the receiver end: [0, 0, 0, 0]. (b) If the user A has data bit 0 to send, then what will be the corresponding chip code / sequence generated by A?
