The phrase 'waveform design and diversity' refers to an area of radar research that focuses on novel transmission strategies as a way to improve performance in a variety of civil, defense and homeland security applications. Three basic principles are at the core of waveform diversity. First is the principle that any and all knowledge of the operational environment should be exploited in system design and operation. Second is the principle of the fully adaptive system, that is, that the system should respond to dynamic environmental conditions. Third is the principle of measurement diversity as a way to increase system robustness and expand the design trade space. Waveform design and diversity concepts can be found dating back to the mid-twentieth century. However, it has only been in the past decade or so, as academics and practitioners have rushed to exploit recent advances in radar hardware component technology, such as arbitrary waveform generation and linear power amplification, that waveform diversity has become a distinct area of research. The purpose of this book is to survey this burgeoning field in a way that brings together the diverse yet complementary topics that comprise it. The topics covered range from the purely theoretical to the applied, and the treatment of these topics ranges from tutorial explanation to forward-looking research discussions. The topics treated in this book include: classical waveform design and its extensions through information theory, multiple-input multiple-output systems, and the bio-inspired sensing perspective; the exploration of measurement diversity through distributed radar systems, in both cooperative and non-cooperative configurations; the optimal adaptation of the transmit waveform for target detection, tracking, and identification; and more. This representative cross-section of topics provides the reader with a chance to see the three principles of waveform diversity at work, and will hopefully point the way to further advances in this exciting area of research.

An iconic rock DJ of the Twin Cities tells her harrowing story of being stalked while living her very public life

What’s it like to be in the public spotlight when it just might get you killed? For Mary Lucia, becoming a wildly popular rock DJ meant connecting with a multitude of fans through a shared love of music and deep cuts. But for one listener, that connection became a dangerous obsession, catapulting Lucia into the terrifying three-year nightmare that she chronicles in this raw, wry, and profoundly courageous memoir. With electrifying wit and anger, Lucia shares her experience of navigating constant terror while life absurdly goes on: interview rock stars, curate a radio show song list, judge high school battles of the band, kick a drug addiction cold turkey . . . all while fearing what might be waiting in her mailbox or who might be waiting on her front step or at her back door.

 

Lucia was no stranger to inappropriate or weird contact from fans, but things turned sinister when ten pounds of raw meat were delivered to her at work, followed by a steady stream of ominous letters, cards, packages, and messages. When the letters included threats to her dogs’ safety, she tried to get help, but without a name and return address on these communications there was nothing she could do. As the stalker’s actions escalated, Lucia felt more and more isolated. Police responding to her 911 calls were insensitive and dismissive, and even her friends implied that being stalked was just a hazard of her high-profile job and her high-energy personality. No one seemed to take seriously the danger she faced.

 

Inseparable from this ordeal is the story of how Mary Lucia became the notorious radio malcontent known by so many avid listeners. From the good, bad, and weird of growing up in her eccentric family to drugs, death, and dogs, Lucia finally shares her life on her own terms in What Doesn’t Kill Me Makes Me Weirder and Harder to Relate To. Applying her signature dark humor to her own traumatic experiences, Lucia’s memoir is idiosyncratic, bold, and—ironically—relatable.

This book presents a state of the art review of integrated circuits, systems and transceivers for wireless and mobile communications. Contributions from world-class researchers focus upon the most recent developments in key RF, IF and baseband components and subsystems and transceiver architecture in CMOS technology. Adopting a top-down approach from wireless communications systems, mobile terminals and transceivers, to constituent components, this book covers the whole range of baseband, IF and RF issues in a systematic way. Circuit and system techniques for design and implementation of reconfigurable low voltage and low power single-chip CMOS transceivers for both mobile cellular and wireless LAN applications are included.

Practical lessons and approaches in radio receiver design for wireless communication systems are the hallmarks of Wireless Receiver Design for Digital Communications, 2nd Edition. Decades of experience 'at the bench' are collected within and the book acts as a virtual replacement for a mentor who teaches basic concepts from a practical perspective and has the war stories that help their 'apprentice' avoid the mistakes of the past.

The crucial decade for the development of the domestic wireless was 1924-34. At the beginning of the period most receivers in Britain were crystal sets, but by the end nearly all sets were on the mains, using valves and mostly with superhet circuits-broadly the same as those in use today.

Posthumously inducted into the National Radio Hall of Fame in 2007, Richard Durham creatively chronicled and brought to life the significant events of his times. Durham's trademark narrative style engaged listeners with fascinating characters, compelling details, and sharp images of pivotal moments in American and African American history and culture.

In Word Warrior, award-winning radio producer Sonja D. Williams draws on archives and hard-to-access family records, as well as interviews with family and colleagues like Studs Terkel and Toni Morrison, to illuminate Durham's astounding career. Durham paved the way for black journalists as a dramatist and a star investigative reporter and editor for the pioneering black newspapers the Chicago Defender and Muhammed Speaks. Talented and versatile, he also created the acclaimed radio series Destination Freedom and Here Comes Tomorrow and wrote for popular radio fare like The Lone Ranger. Incredibly, his energies extended still further--to community and labor organizing, advising Chicago mayoral hopeful Harold Washington, and mentoring generations of activists.

Incisive and in-depth, Word Warrior tells the story of a tireless champion of African American freedom, equality, and justice during an epoch that forever changed a nation.
