DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable measurement applications. The device features a
powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to ACtive mode in less than 1 μs.
The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16-
bit timers, up to 24 I/O capacitive-touch enabled pins, a versatile analog comparator, and built-in communication
capability using the universal serial communication interface. In addition the MSP430G2x53 family members
have a 10-bit analog-to-digital (A/D) converter. For configuration details see Table 1.
Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values,
and then process the data for display or for transmission to a host system.
High-Speed, Low-Power
Dual Operational Amplifier
The AD826 features high output current drive capability of
50 mA min per amp, and is able to drive unlimited capacitive
loads. With a low power supply current of 15 mA max for both
amplifiers, the AD826 is a true general purpose operational
amplifier.
The AD826 is ideal for power sensitive applications such as video
cameras and portable instrumentation. The AD826 can operate
from a single +5 V supply, while still achieving 25 MHz of band
width. Furthermore the AD826 is fully specified from a single
+5 V to ±15 V power supplies.
The AD826 excels as an ADC/DAC buffer or ACtive filter in
data acquisition systems and achieves a settling time of 70 ns
to 0.01%, with a low input offset voltage of 2 mV max. The
AD826 is available in small 8-lead plastic mini-DIP and SO
packages.
The contemporary view of the Smart City is very much static and infrastructure-
centric, focusing on installation and subsequent management of Edge devices and
analytics of data provided by these devices. While this still allows a more efficient
management of the city’s infrastructure, optimizations and savings in different do-
mains, the existing architectures are currently designed as single-purpose, vertically
siloed solutions. This hinders ACtive involvement of a variety of stakeholders (e.g.,
citizens and businesses) who naturally form part of the city’s ecosystem and have an
inherent interest in jointly coordinating and influencing city-level activities.
New applications such as video conferencing, video on demand, multi-
media transcoders, Voice-over-IP (VoIP), intrusion detection, distributed
collaboration, and intranet security require advanced functionality from
networks beyond simple forwarding congestion control techniques.
The focus of this book is on developing computational algorithms for transmit wave-
form design in ACtive sensing applications, such as radar, sonar, communications and
medical imaging. Waveforms are designed to achieve certain desired properties, which
are divided into three categories corresponding to the three main parts in the book,
namely good aperiodic correlations, good periodic correlations and beampattern match-
ing.
Wireless communications, together with its applications and underlying technologies, is
among today’s most ACtive areas of technology development. The very rapid pace of im-
provements in both custom and programmable integrated circuits for signal processing ap-
plications has led to the justfiable view of advanced signal processing as a key enabler of the
aggressively escalating capacity demands of emerging wireless systems. Consequently, there
has been a tremendous and very widespread effort on the part of the research community
to develop novel signal processing techniques that can fulfill this promise.
This chapter provides extensive coverage of existing mobile wireless technologies. Much of the
emphasis is on the highly anticipated 3G cellular networks and widely deployed wireless local
area networks (LANs), as the next-generation smart phones are likely to offer at least these two
types of connectivity. Other wireless technologies that either have already been commercialized or
are undergoing ACtive research and standardization are introduced as well. Because standardization
plays a crucial role in developing a new technology and a market, throughout the discussion
standards organizations and industry forums or consortiums of some technologies are introduced.
In addition, the last section of this chapter presents a list of standards in the wireless arena.
