LTE and Bluetooth in-device coexistence with WLAN
Modern mobile phones can support cellular and noncellular wireless communications standards at the same time. This means, however, that the subsystems must operate in very close proximity to each other within a single device (in-device coexistence). The resulting high level of reciprocal leakage can at times cause considerable interference. This application note employs preliminary theoretical analysis and demonstrates how the problems of in-device coexistence can be measured. Exemplary, the effects of LTE and Bluetooth(r) traffic on the WLAN performance of a commercially available smartphone are examined. These examples will also enable the reader to design tests for complementary scenarios.

Faster, Better, and Cheaper Alternatives to FPGA-based Accelerators
Even as the number of cores in general-purpose CPUs continues to climb, many difficulties remain in building systems that are capable of handling large volumes of network data. This is due to several factors, including the ever-increasing rate of network traffic and some fundamental limitations in general-purpose computing architectures. System designers are constantly seeking ways to expand their system capacity beyond such limitations.

Critical Techniques for High-Speed A/D Converters in Real-Time Systems
An A/D (Analog-to-Digital) converter, frequently abbreviated as ADC, accepts an analog voltage at the input and produces a digital representation of that voltage at the output that's called a "sample". The two primary characteristics of A/Ds are the rate of conversion or sampling rate, expressed in samples per second, and the accuracy of each digital sample expressed as the number of binary bits or decimal digits per sample.

Software Defined Radio Handbook (11th Edition)
SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing. This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.

Putting FPGAs to Work in Software Radio Systems (Ninth Edition)
Preface FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.

High-Speed Switched Serial Fabrics Improve System Design (Seventh Edition)
As evolutionary enhancements to the venerable VMEbus, both VXS and VPX deliver significant improvements in data bandwidth, connectivity, power distribution, and cooling. When VME was first introduced, its shared bus backplane interboard transfer rates of 30 or 40 MBytes/sec were more than adequate for most applications. As requirements grew, VME acquired new interfaces such as VSB, RACEway, RACE++, VME64, VME320, and 2eSST, thereby ensuring a healthy community of suppliers and a new stream of products.

Don't Fear the Future Plan a Scalable Long-Term Cellular Strategy for 2G, 3G, and 4G Technology
When does it make sense to begin planning to support newer 3G and 4G services? There is no single correct answer. Different approaches will make sense for different customers in different markets. There are, however, some important factors to consider when evaluating the possible approaches, especially if you are weighing 2G versus 3G technology for your M2M solution. To best plan ahead, adopt a scalable approach that will allows you to address all markets 2G, 3G, and 4G as cost effectively as possible.
