RGB

The system simulation I have made is about Transceiver system. It s about Direct Sequence CDMA + Ultra Wide Band Simulation,which computing BER vs SNR to display the system performance. Main Program is in maindsuwb.m, you can run the overall system to display the system performance from maindsuwb.m.

this program is for on-off-keying signalling modulation.

For example, heating up the temperature in a room is a process that has the specific, desired outcome to reach and maintain a defined temperature (e.g. 20°C), kept constant over time. Here, the temperature is the controlled variable. At the same time, it is the input variable since it is measured by a thermometer and used to decide whether to heat or not to heat. The desired temperature (20°C) is the setpoint. The state of the heater (e.g. the setting of the valve allowing hot water to flow through it) is called the manipulated variable since it is subject to control action
