Introduction to the Digital Communications. The sampling theorem. Quantization: quantizing noise, uniforme quaintizing, adaptive quantizing, vector quantizing. Source coding: lossless coding. Channel coding: block codes (generator matrix, parity-check matrix, syndrome testing, error correction), convolutional codes: connection representation, impulse response, state diagram, tree diagram, trellis diagram, the Viterbi algorithm.  Multiplexing: FDM, TDM, CDMA. Spread Spectrum Techniques: direct-sequence spread-spectrum systems, frequency hopping systems, sincronization)

A1. Lectures with big group of students  

They are based in the explanation of the theory concepts, exercises and practical problems of the course.

All the contents of the subject appear in English in the bibliography. Moreover, exists plenty of information available in Internet.

A2. Lectures with practical groups

They are developed in the lab, and they are based on the implementation of Android applications by the students.

A3. Collective tutorial classes

They are based on seminars and doubt resolution of the students.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

Once the semester is finished, the student can choose between two kinds of evaluation: OVERALL or ONLY EXAM.

OVERALL EVALUATION

This kind of evaluation is organized using the activities described in the previous table.

The exam of the subject will evaluate the theoretical and operating parts (S2 and S3). The student must demonstrate to have acquired the subject competences. This final exam will be weighted as the 50% of the evaluated parts (S2 and S3). The exam does not include the practising part that is evaluated after finishing each practising. Students who have marks higher or equal to 5.0 out of 10 in the practising part of the OVERALL EVALUATION do not have to make the laboratory practising exam in the ONLY EXAM evaluation

In order to pass the subject, the following conditions must be fulfilled:

1)       The student must have a mark higher or equal to 4.0 out of 10 in the exam (S2 and S3 parts).

2)       The student must have a mark higher or equal to 4.0 out of 10 in the practising part.

3)       The student must have a global mark higher or equal to 5.0 out of 10.

The marks obtained in each part of the overall evaluation are valid during the same academic year.

The student can resign the overall evaluation at any moment, but from then, the kind of evaluation ONLY EXAM will be the chosen evaluation for the rest of the course.

ONLY EXAM EVALUATION

This kind of evaluation is organized in an only exam in which all parts of the subject are evaluated. The final exam is weighted in the following way:

-           S2 Theoretical concepts and S3 Exercises, cases and works: 70%.

-           S4 Laboratory practising: 30%.

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 at each part of the final exam.

Those parts with a mark higher or equal to 5.0 are maintained during the same academic year.

DETAILS OF THE EVALUATION

The overall evaluation is based on the next aspects:

• S1, Attendance and active participation (10%)
• S2, Theoretical concepts (30%)
• S3, Exercises, cases and works (30%)
• S4, Laboratory practising (30%)
