  • Cellular Systems Modems

    A modem is an electronic device that helps to modulate and demodulate the information at the transmitter and receiver block respectively in order to transmit the information signal reliably through the propagating medium. Initially a modem was also known as 'data phone', as it enabled a computer terminal (host) to send and receive information over public switched telecommunications networks (PSTNs) by converting the digital data of a computer terminal into an analog signal used on telephone phone lines and then converting it back to its original form once it was received at the other end. These modems are commonly known as 'dialup modems'. Wireless modems work in the same way as a dialup analog modem, except they convert digital data into radio signals for transmission through air. This chapter discusses how the cellular systems including mobile phone modem system has been evolved over several generations and also discusses the legacy modems.

  • Smartphone Hardware and System Design

    A smartphone contains several components including processors. It incorporates the functionalities of a handheld computer to run different user applications along with the functionalities of a cellphone modem. This chapter shows the different modules of a smartphone and lists different hardware components. It discusses these components in more details. The baseband part is responsible for a cellular system's modem bit detection, bit transmission, protocol processing, sleep and power management, audio processing, and so forth, and the application part is responsible for running different applications. The baseband modem manages radio communications, signal processing tasks, and protocol stack to enable the smartphone to access different types of wireless network technologies. The application unit relies mainly on a general purpose processor (GPP), most commonly a reduced instruction set computers (RISC) processor, which provides the processing needed by the applications and provides user interfaces and overall command‐and‐control functions.

  • DSL Technology – Broadband via Telephone Lines

    Digital subscriber line (DSL) technology transmits broadband data over telephone lines. With approximately 480 million DSL lines in service at the end of 2012, DSL technology is the most popular form of broadband access in the world. The use of existing telephone lines for DSL technology provides several benefits. There are economic benefits from using existing facilities between the network and the home, as well as sharing these facilities with the existing voice/fax services. The fundamental advantage of DSL technology over voice‐band modem technology is the expanded frequency bandwidth of the transmission channel. Specifically, the analog‐to‐digital conversions at the local digital telephone switches are excluded from the DSL transmission channel. Several types of DSL technology have evolved, with a trend toward higher bit rates. The standardized and widely deployed types of DSL technology are described in this chapter.

  • LTE UE Operations Procedures and Anatomy

    Once the user equipment (UE) is powered ON, it triggers the CPU reset and initially it performs the booting and system initialization related tasks including device self‐test. In the modem unit, once the system initialization is over and operating system (OS) is loaded into the memory, then OS takes the control and starts executing different tasks, where different modem sublayers and procedures are running as OS threads. In order to synchronize time and frequency with a UE cell the eNB broadcasts two types of downlink physical signals: a primary synchronization signal (PSS); a secondary synchronization signal (SSS). These two signals were especially designed to enable time and frequency synchronization. They also indicate physical layer cell identity, cyclic prefix length, and frequency division duplex (FDD), or time division duplex (TDD) mode used in the cell.

  • Modem Layer

    The digital modulation schemes require the physical layer (PHY) of a wireless Internet of Things (IoT) standard to utilize digital signal processing (DSP) in order to implement Modulation and Demodulation (MODEM) of the waveform. This chapter discusses the various waveforms employed by wireless IoT standards and their advantages and disadvantages. It describes how the selection of those waveforms is often driven by the desired application and transceiver hardware. The chapter establishes the model of a complex‐valued baseband signal including noise. IoT standards generally require some form of pulse shaping. Linear modulation occurs when the modulating signal is multiplied on to the amplitude of the carrier signal. Angular modulation occurs when the modulating signal is applied to the angle, or phase, of the carrier signal. Frequency‐shift keying and differential phase shift keying both employ a non‐zero time derivative to the phase of the signal.

  • Digital Modulation/Demodulation for Mobile Radio Communication

    This chapter describes some digital modulation methods in order of appearance: digital modulation for analog FM systems, spectrum‐efficient digital FM, linear modulation, spread spectrum system, multicarrier transmission, and single‐carrier frequency‐division modulation. Special requirements for digital mobile radio communication are stable performance of bit error rate in fast‐fading channels and cochannel interfering environments, low power consumption, as well as size and cost‐effectiveness of equipment. The chapter also describes linear modulation/demodulation systems. The spectrum of linearly modulated signals is given by translating the modulating baseband signal spectrum into the carrier frequency. In spread‐spectrum systems the spectrum is spread by introducing additional modulation with SS codes. In this system, digital signals are transmitted in parallel using multiple carriers with different frequencies. The single‐carrier frequency‐division modulated signal recently shows a spectrum that is divided into several separated frequency regions and spreads by putting null spaces in the frequency domain.
