Summary:

This two-day course provides a review of the system architectures, principles involved, techniques applied, and performance achieved in UMTS’s Long Term Evolution (LTE) mobile broadband access (MBWA) system. The typical types of packet switched data conveyed by this system is studied. Key enabling technologies are presented including: relevant digital modulation techniques, error detection/correction methods, and multiple access and NLOS techniques employed in Point-to Multipoint (PMP) systems. The non-line-of-sight (NLOS) mobile wireless fading path is reviewed and a coverage example provided. Key physical layer and MAC features are presented. The key parameters of LTE’s UMTS predecessor, HSPA and LTE are compared. Finally, the status of LTE is summarized and its key parameters compared to Mobile WiMAX .

Learning Objectives:

Upon completing the course, the participant will be able to:

Understand the relationships between the ITU’s IMT-2000, ETSI, UMTS 3GPP group, and HSPA/LTE.
Describe the structure of various forms of packet switched data signals conveyed by MBWA systems such as IP, VoIP, Mobile IP, and Ethernet.
Be familiar with the operation, spectral density, and bit error rate (BER) performance of digital modems employing BPSK, QPSK, 16QAM and 64QAM.
Understand the various path loss and fading phenomena possible over a mobile NLOS wireless channel.
Understand the basics of Block, Convolution, and Turbo codes and how these codes are applied to improve the BER performance of LTE systems.
Be familiar with the various techniques required for PMP communications, such as Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD), and non-line-of-sight (NLOS) methods including Orthogonal Frequency Division Multiplexing (OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Scalable OFDMA (S-OFDMA), Single Carrier-Frequency Division Multiple Access (SC-FDMA), Adaptive Antenna Systems (AAS), Antenna Diversity Systems including Delay Diversity (DD), Cyclic Delay Diversity (CDD), Space Time Block Coding (STBC) and Space Frequency Block Coding (SFBC), and Multiple Input/Multiple Output (MIMO) systems.
Develop a firm understanding of the system architecture, key features, specifications and performance parameters of LTE.

Target Audience:
