1 Understanding LTE with MATLAB an overview By: Houman Zarrinkoub PhD.
2 Motivations Why LTE? Delivers global broadband mobile communications for 21 st century Features innovative new air interface technologies OFDMA, MIMO, Fast link adaptations Achieves remarkable performance Basis of 4G wireless technology Has staying power for even 5G technologies and beyond Every communications engineer should know something about it My favorite reason: Puts Fourier analysis and in general Math back in telecommunications
3 Motivations Why LTE with MATLAB? Underlying transmission technologies has deep mathematical roots Dynamic nature of LTE transceiver system is best understood and revealed through simulation MATLAB provides a natural language and environment for mathematical modeling and simulation Area of author s expertise
4 Overview of chapter 1 Introduction
5 Evolution of wireless standards * *Although ETSI the European standardization body started GSM, later ETSI and other standard bodies formed 3GPP and 3G and 4G standards were developed globally by 3GPP. For a while a standard body known as 3GPP2 competed with 3GPP and developed North American 3G CDMA standards based on IS-95 but 3GPP2 finally dissolved in 2005
6 LTE Requirements Improved system capacity and coverage High peak data rates Low latency (both User-plane and Control-plane) Reduced operating costs Multi-antenna support Flexible bandwidth operations Seamless integration with existing systems (3G, WiFi, etc.)
7 Evolution of LTE LTE (Release 8) was completed in 2008 LTE (Release 9) released in 2009 with minor modifications to Rel. 8 LTE-Advanced = LTE-A = LTE Release 10 A maximum peak data rate of 1 Gbps approved by the ITU as an IMT-Advanced technology
8 History of peak data rates Technology Theoretical peak data rate (at low mobility) WCDMA (UMTS) HSDPA (Rel 5) HSPA+ (Rel 6) WiMAX (802.16e) LTE (Rel 8) WiMAX (802.16m) LTE-Advanced (Rel 10) 1.92 Mb/s 14 Mb/s 84 Mb/s 26 Mb/s 300 Mb/s 303 Mb/s 1 Gb/s
9 LTE enabling technologies Air interface Downlink: OFDMA Uplink: SC-FDMA Multi-antenna (MIMO) techniques Defining multiple transmission modes Link adaptation Adaptive modulation & coding Adaptive precoding Adaptive MIMO (ranks or number of layers) Flexible bandwidth allocation Computationally efficient Turbo Coding

14 FDD & TDD FDD: Frequency Division Duplex frequency bands are paired simultaneous transmission on two frequencies (one for downlink and the other for uplink) TDD: Time Division Duplex frequency bands are unpaired uplink and downlink transmissions share the same channel and carrier frequency The transmissions in uplink and downlink directions are timemultiplexed H(f) (0,0) H(f) F c (UL) Uplink (UL) Operating band F c (UL)=F c (DL) (0,0) Downlink (DL) & Uplink (UL) Operating band F c (DL) Downlink (DL) Operating band
