| Objective : | The course presents communication systems, emphasizing wireless systems applied within mobile phones, digital audio, digital TV and wireless computer networks. The systems are characterized from their communication channels and modulation methods. A review of the presently most important wireless stan-dards is given. Tools for planning and verification of a wireless network coverage of a physical environment is introduced, including the characterization of the problems encountered when different wireless networks must co-exist in the ISM (Industrial, Scientific and Medical) band. Examples of applications of wireless networks are given, including the application within indoor localization of mobile terminals. In the course a digital communication system is simulated in Matlab, among others by using the Communications Toolbox. Having passed the course, the student will be able to accomplish the following, within the areas shown below: Communication Channels. Prepare model for link budget and compute the link budget for wireless communication channels, corresponding to the specific course contents. Communication Methods. Prepare model for and analyze the communication methods, corresponding to the specific course contents. Communication Standards. Explain and evaluate a selection of communication standards, corresponding to the specific course contents. Co-Existence of the Communication Standards. Is able to assess the consequences of the simultaneous application of different wireless communication standards, covering the same physical environment, corresponding to the specific course contents. Communication Systems. Is able to apply Matlab for simulation of the properties of a communication system, corresponding to the specific course contents. Is able to discuss the application of communication systems, corresponding to the specific course contents. |

| Principal Content : | Digital communication methods: OFDM (Orthogonal Frequency Division Multiplexing), CDMA (Code Division Multiple Access), FDMA (Frequency Division Multiple Access), TDMA (Time Dision Multiple Access), UWB (Ultra Wide band). Fixed-wire communication standards: xDSL (Asymmetric Digital Subscriber Line). Wireless Communication standards: DAB (digital audio); DVB (digital TV); Wireless Local Area Networks, WLAN, (IEEE 802.11b, g, n); Wireless Personal Area Networks, WPAN, Bluetooth (IEEE Std. 802.15.1); WPAN Zigbee (IEEE Std. 802.15.4), including the introduction of wireless sensor networks. The wireless communication channel: In- and outdoor propagation, short and long term fading and shadow fading, Dopplershift, linkbudget, BER (bit error rate). Co-existence of wireless networks in the ISM band at 2.4 GHz. Brief introduction to antennas for short range, wireless communication systems. Geographical localization of mobile terminals, including brief introduction to tool for planning and validation of short range wireless networks. |

| Teaching method : | Sessions in class with active participation by the students. The time will be divi-ded between lectures and presentations prepared by the students. During the course the students (individually or in groups of two) are required to prepare and deliver a presentation of material from the course curriculum. Furthermore du-ring the course, each student or groups of two students, prepares a simulation of a communication system using Matlab and the Communications Toolbox. | ||
| Required prequisites : | The DCM and DCEC must be passed to register for the oral exam. | ||
| Recommended prerequisites : | - None | ||
| Relations : | - EWWL uses the prerequisites obtained in EDCM and EDCEC. | ||
| Type of examination : | Look under remarks | ||
| External examiner : | Internal | ||
| Marking : | 7 step scale | ||
| Remarks : | - Oral examination based on a presentation prepared by the students, and discus-sion of a subject selected by random from a set of subjects. The presentations above, might naturally form the basis for the oral exam presentation. Please noti-ce that this is not a group examination. - 7 step marking 3 steps of this marking scale are described as follows: 12 is given for the excellent presentation, which completely fulfills the course goals, with no or very few errors of marginal importance. 7 is given for the average presentation, which fulfills the course goals, with some errors in the presentation. 02 is given for the minimum acceptable presentation, which fulfills the course goals. - |
