Lab 1: Modulation and SNR

Introduction 

In this lab, you will learn how to implement a simulator for simple narrow-band communications. You will learn how to generate Gaussian random channels and noises, how to modulate/demodulate samples and how to decode samples. You will also need to derive the expected SNR, SER and data rate.

Files to submit

• mod_demod.m
• report.pdf (including all figures along with captions and your summarization)

Figures to show

• Constellation points for every different link distsance
• SNR bar graph
• SER bar graph
• data-rate bar graph

See details in lab1_info.pdf in new E3.
