Computer Use: MATLAB

Laboratory Projects: Students will work in groups of two. The first project will be a comprehensive design project lasting 4 weeks and requiring a detailed report. The other two projects will last 2 weeks.

  1. Design of a phase lock loop for phase or frequency recovery. Effect of noise.
  2. Design of binary receiver. Monte Carlo simulation of the probability of error and comparison to its theortical value.
  3. 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.
