This the simulink file that demonstrates the fundametal principle of operation behind asynchronous CDMA systems using Welsh codes. The system performance can be evaluated by changing the processing gain at the transmitter and by increasing or decreas

This paper studied the carrier-frequency offset effect on the performance of asynchronous multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) systems with aperiodic random spreading and correlated Rayleigh fading. This paper also
