lasting 4 weeks and requiring a detailed report. The other two projects
will last 2 weeks.
- Design of a phase lock loop for phase or frequency recovery. Effect of noise.
- Design of binary receiver. Monte Carlo simulation of the probability of error and comparison to its theortical value.
- Simulation of an intersymbol interference channel. Sensitivity of the eye diagram to timing errors. Design of a simple equalizer.
Engineering Design Statement: The computer
laboratory projects will consist of designing, simulating and
evaluating the performance of components of analog and digital
communications receivers operating in noise.
