Subject Area	Communications
Course Prerequisites	Credit in ECE 459
Course Directors	Steven J Franke
Description	The focus of this laboratory course is digital communications systems. Students will gain hands-on experience in the configuration and performance evaluation of digital communication systems employing both radio and optical signals.
Credit	2 hours
Topics	Spectrum Analyser tutorial, power spectral-density measurements Baseband antipodal signaling Observe and characterize envelope, spectrum, eye patterns Bit-error-rate vs. Eb/No, clock timing error with matched filter Bit-error-rate for sub-optimum filters Coherent RF Communications - BPSK Observe and characterize envelope, spectrum, eye patterns Bit-error-rate vs. Eb/No, carrier phase error Carrier synchronization using Costas loop for BPSK Characterization of loop components: VCO gain constant phase detector gain constant loop filter Steady-state loop performance Dynamic performance of carrier recovery loop-step response, loop transfer function Effect of noise on loop performance Noncoherent RF communications - DPSK Observe and characterize envelope, spectrum, eye patterns Measure bit-error-rate vs. Eb/No, delay error for delay and multiply detection Clock timing recovery using PL BPSK and DPSK performance in the presence of a CW jammer Fiber-optic communications Measurement of signal, noise power Characteristics of noise Observe and characterize eye patterns, bit-error-rate for high-speed optical link
