Objectives
To present the fundamentals of digital modulations and spread spectrum techniques.
Program
Topic 1: Bandpass transmission (digital modulations):
binary digital modulation techniques(PSK, FSK, ASK); coherent and noncoherent detection of PSK and FSK signals; DPSK; error probability in binary digital modulations; nonbinary digital modulations (MPSK, MFSK and QAM); symbol and bit error probabilities in MPSK, MFSK and QAM; spectral efficiency.
Topic 2: Spread Spectrum:
introduction and generic considerations; spread spectrum techniques: direct sequence (DS) and frequency hopping (FH); pseudo-random sequences (PN, Gold and Kasami sequences); multiple access (CDMA).

Teaching methods and learning activities
- theory is presented in lecture classes;
- exercise solving and interaction with the teacher occur in theoretical-practical classes; students will be given a set of exercises to be solved in class and at home.
- Matlab/Simulink simulation work will be developed in 2-hour lab classes.
Evaluation Type
Distributed evaluation without final exam

Eligibility for exams
Not to be absent more than the allowed number of times stated in "Normas de Avaliação".
Calculation formula of final grade
CF=0,35 x (MT1+MT2) + 0,3xAC
CF - final grade
MT1 and MT2 - mini-test grade
AC - continuous evaluation grade.
Continuous evaluation is accomplished during Lab Classes and is based on the student's performance on Lab work and reports.
To pass the course the average mini-test grade may not be lower than 35% of total grade (7 in 20).
