The LTE-Advanced standard has been adoptedworldwide as the fourth generation mobile communication technology. LTE systems use Orthogonal Frequency Division Multiplexing (OFDM) as the downlink radio access interface to support multiple users providing higher data rates comporedto 2G and 3G networks. OFDM provides better equalization capability to the LTE network to overcome channel fading effects which would be a major issue in previous single carrier systems when operated at high symbols rates. The use of multi carrier system also supports well the scalable bandwidths from 1.4 MHz to 20 MHz in LTE networks. This project requires students to study the several types of modulation schemes used with OFDM technology in the downlink of LTE systems. Students are expected to discuss how various modulation schemes are chosen according to the required user data rate and channel conditions. This assignment exposes the student to real-world applications of digital communication in mobile wireless communication. In doing so the student shall acquire skills to understand the real-world requirements, critically review the existing techniques and write a technical report based on his or her investigation. Requirements The student needs to write a report addressing the following areas: • Introduction, key features and structure of LTE system. • Analyze how digital modulation is adapted in OFDM technology according to the different channel conditions and user data rates?   Marking criteria Section to be included in the report Description of the section Marks Introduction A high-level description as introduction demonstrating the understanding of the case study. 5 Literature review Identify different types of modulation schemes and symbol constellations sizes used in LTE downlink 20 Requirement Identify the advantages of OFDM technology, how different types of modulation schemes are supported by OFDM technology. 20 Critical analysis Analyze how different modulation schemes are chosen according to the user requirement and channel conditions 25 Reference style IEEE 5 Conclusion Properly concluding remarks 5 Poor writing Inadequate structure, careless presentation, typos, or the report exceeds the word limit by more or less than 10% -30 Plagiarism Type of plagiarism – Copy from other students – Copy from internet source/textbook – Copy from other sources -80 Total 80   Marking Rubric for Exercise Answers Grade Mark HD 80%+ D 70%-79% CR 60%-69% P 50%-59% Fail < 50% Excellent Very Good Good Satisfactory Unsatisfactory Evaluation Logic is clear and easy to follow with strong arguments Consistency logical and convincing Mostly consistent and convincing Adequate cohesion and conviction Argument is confused and disjointed Sophistication and effectivity The presented solution demonstrated an extreme degree of sophistication and effectivity to secure and/or manage WLAN The presented solution demonstrated a high degree of sophistication and effectivity to secure and/or manage WLAN The presented solution demonstrated an average degree of sophistication and effectivity to secure and/or manage WLAN The presented solution demonstrated a low degree of sophistication and effectivity to secure and/or manage WLAN The presented solution demonstrated a poor degree of sophistication and effectivity to secure and/or manage WLAN.
