Module goal - Knowledge and skill to be achieved by students
  The goal of the course is to enable students to master the necessary theoretical knowledge in fields of estimation of signal parameters in the channel under complex influence of multiplication and additive noise from aspect of optimum design of the multiple approach model with focus on CDMA concept and with application in mobile networks, as well as decrease of impact of noise using managed antenna systems.

Syllabus
  Model of encoded multiple access, CDMA, in mobile communications: techniques of spectrum widening and encoded processing using pseudo generators, rake receiver, managing the signal power, soft and hard handover, Radio network architecture for universal mobile telecommunication systems (UMTS): mobile terminals, base point (NodeB) and radio network controller (RNC), physical channels and channels for transmission of information content, classes and types of services, procedures for channel allocation. Functions and tasks of the CDMA receiver: acquisition of channel fading, estimation of channel parameters, selection of the optimal channel speed, estimation of signal-interference ratio and power management in the channel, decoding. Link resources and predicting parameters and reliability of signal coverage, calculation of channel capacity for inlet and outlet traffic. Technique of transmitter diversity: open loop and closed loop. Techniques of time division duplex –TDD: joint detection and joint transmission. Techniques of multiple user detection in broadband CDMA systems: removing effects of parallel and serial interference. Adaptive antenna systems for improvement of parameters and reliability of signal coverage as well as increase of the channel capacity: techniques of receiver diversity, space-time rake receiver, technique of transmitter diversity for multiple antenna queues.

Didactic methods
  Lectures are performed directly in an aula. Each lecture is followed by description and solution of problems performed by the lecturer with goal of enabling students to master mathematical tools and methods introduced during lectures, on which the analyzed theoretical models of estimation and improvement of the system features are based. <br>
During tutorials, under tutor guidance and supervision, other examples and problems will be solved, as well as exam problems, and the ideas for solving of the problems presented during exercises will also be presented. In this way even during the execution of the curriculum it will be possible to continually check the degree of preparedness of students to approach the final exam. As part of laboratory exercises the students will use MATLAB simulator in order to familiarize with basic features of the processes in physical canals and data canals, and will also approach the development of simple applications in the observed field. Special attention will be paid to possibilities of the antenna systems with goal of improvement of th features of CDMA transmission. <br>

Exams
  During the course students earn points according to the following system: <br>
- Attending classes and tutorials: 10 points, student with more then three absences from lectures and/or tutorials can not get these points. <br>
- Home assignments and laboratory exercises bring maximum of 10 points, assuming solving 5 to 10 assignments equally distributed throughout the semester. <br>
- Partial exams: two partial exams; each positively evaluated partial exam 20 points. Each partial exam lasts 90 minutes and it is structured as follows: <br>
- Answering to simple questions with goal of testing whether student has basic theoretical knowledge; students with correct answers to all such questions earn 5 points; <br>
- Solving an open answer problem, with correct answer bringing 10 points; <br>
- Solving problems with multiple answers offered, on of answers being the correct one; students with correct answers to all such questions earn 5 points; <br>
Students who earned less then 20 points during the semester must retake the course. Students who earned 40 or more points during the semester will take a final exam; This exam consists of discussion of problems from partial exams, home assignments and answers to simple questions related to course topics. <br>
Final oral exam provides maximum of 40 points. In order to get positive final grade, students must earn minimum of 20 points in this exam. Student failing to earn the minimum must take the makeup oral exam. Student who earned 20 or more, and less then 40 points during the semester, will have to take the makeup exam. <br>
The makeup exam is organized in the following manner: <br>
- Written part structured similarly to partial written exam, during which students solve problems in topics they failed on partial exams (less then 10 points); <br>
- Oral part structured the same as the oral part of the final exam. <br>
Only students who managed to earn total score of 40 or more points in written part of the makeup exam will be allowed to take the oral part of the makeup exam, where the mentioned score consists of points earned through attending lectures, solving home assignments, passing partial exams and passing the written part of makeup exam. Oral makeup exam provides maximum of 40 points. In order to achieve positive final grade students must earn minimum of 20 points in this exam. Student failing to earn the minimum will have to retake the course. Oral makeup exam gives maximum of 40 points. In order to achieve positive final grade students must achieve minimum of 20 points in this exam. Student failing to achieve the minimum will have to re-enroll for this course. <br>

Aditional notes
  During the written part of the exam students are allowed to use a list of formulas prepared by lecturers, which may be of use in solving problems. It is not allowed to use other notes, books, cell phones or other electronic devices. Problems, which students must solve during the exam, are of the same type solved during the lectures and tutorials.
