Objectives

This course aims to acquaint students with technical knowledge on important aspects of analog and digital communications. At the same time, it also aims to develop students’ personal and professional skills. Two issues are addressed:

1) Acquisition of technical knowledge:

Course themes exposed in tutorial classes include digital transmission of information (quantization, baseband transmission, modulations, synchronization and noise effects in communications). Students will be able to choose the most adequate communication solution and predict problems caused by e.g. intersymbol interference or a high error rate probability. Students get familiar with these concepts in theoretical-practical classes and in laboratory classes.

2) Development of personal and professional attitudes:

Exercises and lab assignments contribute to develop students’ “engineering reasoning and problem solving” and “experimentation and knowledge discovery”.

Learning outcomes and competences

Skills in analog communications, A/D conversion, quantization, digital baseband transmission, digital modulations and digital synchronization (carrier phase recovery and symbol timing recovery).

Working method

Presencial

Program

Digital communications:

1. A/D conversion and quantization
2. Baseband communication
3. Passband communication (with digital modulations ASK, FSK, PSK and QAM)
4. Digital synchronization(carrier phase recovery and symbol timing recovery)

Teaching methods and learning activities

This course is divided into theoretical and laboratory classes. Theoretical classes are based on presentation and discussion of concepts and fundamental techniques. Also some typical problems are discussed and solved. Students will be given a list of problems to solve outside class as practice for the written tests. In laboratory classes (I006 Lab) students will develop and simulate digital communication systems using Matlab/Simulink.

Software

Eligibility for exams

According to the rules, students cannot exceed the absence limit of classes.

Calculation formula of final grade

 

 

FM = 0,65x(T1+T2)/2 + 0,35xDE

• FM: Final Mark

 

• T1 and T2: Tests

 

• DE: Distributed evaluation (average mark of the n-1 best assignments, where n is the number of assignments).

 

• COMMENT 1: All assessment components are based on the scale 0-20.

 

• COMMENT 2: Distributed evaluation is based on students’ performance in practical classes (laboratory) and on students’ assignments and reports.

 

• COMMENT 3: The absence in a Lab class means a zero mark, independently of the absence justification.

 

• COMMENT 4: Students must get a mandatory minimum average mark of 35% in both tests (7.0 out of 20).

 

• Written tests will last 1.30h and will be based on theoretical and theoretical-practical questions. Tests are closed book; however, a formula sheet will be given to the students, who may use a calculator.

 

Special assessment (TE, DA, ...)

Oral or written exam. The distributed evaluation mark will not be taken into account.

Classification improvement

Students can improve their previous mark by solving the two regular tests; the final mark will be computed taking the previous distributed evaluation mark into account.

Observations

Students with a special status (military personnel and working students) and students who attended the course in the previous year (and have got a positive distributed evaluation mark) do not need to attend Lab classes.
