5a. ) As discussed in class, CDMA is a direct-sequencing method that allows simultaneous transmission of data-bits by multiple stations. Given a group of N stations (N 1), CDMA maps each stations data-bit 0/1 onto a unique sequence of discrete changes in signal-levels over multiple time-intervals called chips. The signal sequencing is determined by distinct Walsh-codes assigned to the N stations in a way to meet orthogonality properties during the signal-mixing on physical transmission medium4. Consider two stations S1 and S2 with Walsh-codes + + and + + respectively5. Suppose another station S3 is considered with a CDMA code of + +.
A: For the transmission of binary data 01 by stations S1 and S2 each, show the timing diagram of individual signal levels injected in the medium by S1 and S2;
