Module 5


Wireless communications technology has developed without measure in the past ten years. It’s the era of various advanced wireless technologies like CDMA/WCDMA, WLAN, WiMax, LTE and OFDMA. Software defined radio and cognitive radio technologies are also the upcoming area for better spectrum utilization. As a result of these rapid developments in the field, involved individuals need to build and sharpen their skills for present and future Wireless industries.
All of these capabilities are based on the ability of engineers to design sophisticated RF circuits that are energy efficient, high in performance, small in size, and economically practical.
This course is intended to provide participants with leading edge specialized knowledge in for advancement in career and productivity. The program incorporates basics of digital and wireless communication, latest wireless technologies, such as courses in GSM/UMTS (Global System for Mobile/ Universal Mobile Telecommunication System), IEEE 802.11, IEEE 802.15, WiMax, LTE and other CDMA-specific wireless technologies. With the introduction of the OFDMA 4G technology the courses also address migration from 3G to 4G standards and the 4G techniques. It will provide a brief idea about software defined radio and cognitive radio technology and internet of things. Moreover, the course will provide the participants fundamental principles of RF systems, the design of practical and cost effective RF subsystems, and their translation into practical integrated.

  • Unit 4:Introduction to OFDMA and 4G Systems:

    Learn the fundamentals of OFDMA and the key 4G systems based on this technology. The first part of the course is to understand the basic principles of Orthogonal Frequency Division Multiplexing and its advantages in a mobile system. Different parameters impacting the performance of the OFDMA systems such as Guard time and cyclic extensions, number of subcarriers, synchronization, fundamentals of FFT, optimum timing in presence of multipath, sensitivity to phase noise, time errors and frequency errors will be discussed. The course then provides an overview of Mobile IP followed by the introduction of the major 4G systems such as LTE and WiMAX. The physical layer and channels, Layer 2 and logical/transport channels and signalling are covered. The course concludes with the comparison of the 4G systems.

  • Unit 5:WCDMA & IS-2000 in 3G Systems:

    Gain a basic understanding of various standardization and harmonization initiatives in third generation systems, known as Wideband CDMA and TDD-CDMA. An extensive review of the telecommunications considerations involved in the design and operation of these new specifications in IS-2000 is presented to provide a conceptual background. A thorough discussion of the latest release of the ETSI W-CDMA specification is presented. The features of the W-CDMA standard are compared and related to its predecessors, GSM and IS-95. Finally, concepts, systems architecture and possible applications of the ETSI TDD-CDMA specification are discussed.
