Achieving New Levels of Channel Density in Downstream Cable Transmitter

June 14, 2013

The volume of broadband data transmitted in cable systems has increased tremendously over the last decade. Since 2003, the number of subscribers to broadband data cable services has increased at a compound annual growth rate approaching 14% [1]. The annual growth rate has since slowed, but recent trend information shows double digit growth in premium, so called "wideband" broadband services.

Solutions for Design and Test of Downlink 8x8 LTE MIMO

April 16, 2013
The new application note “Solutions for Design and Test of 8x8 LTE MIMO” is designed to help you get insight into solving tough measurement problems in a unique way for both the design and manufacturing environments by explaining how to combine simulation with test solutions to realize high-performance 8x8 MIMO designs.

Resources to Optimize Your Design for Greater Battery Run-Time

April 16, 2013
Trying to increase battery life? Trying to be green or increase energy efficiency?  If so, then current consumption is most likely one of your key concerns.  Today's multi-tasking, battery-powered devices boast powerful processors, incorporate back-lit touch-screen displays, and have amassed multiple radio receivers and transmitters that are sending and receiving data at unprecedented rates.

Solutions for GNSS Receiver Testing

February 15, 2013
This application note is designed to help you get insight into solving tough measurement problems in a unique way for both the design and manufacturing environments by explaining how to use simulated satellite signals to quickly and accurately verify GNSS receiver operation. The successful proliferation of GNSS receiv­ers worldwide requires today’s engineers to effectively test GNSS receivers with multi-GNSS signals. A real-time GNSS simulator like the N7609B, with its flexibility, func­tionality and performance is well suited to address this task. Combined with the power of an EXG/MXG X-Series signal generator, it provides the real-time simulation of GPS, GLONASS and Galileo L1/E1 signals that is so critical to quickly and accurately testing today’s GNSS receivers.

Testing New-generation Wireless LAN

September 18, 2012

The application note also introduces the WLAN new-generation testing technology of 802.11ac and explains in detail Agilent's 802.11ac software which allows engineers to view and troubleshoot all 802.11ac modulation formats.

Multicarrier TD-SCMA Feasibility

August 13, 2012
There are several options for the architecture of the transmit signal path. The factors that impact transmit signal elements are introduced, followed by a discussion of the different architectures. Figure 1 shows a direct conversion architecture for an initial point of reference only. Section 6 of 3GPP TS 25.105 describes the transmit signal requirements used throughout this discussion.

IMS Architecture: The LTE User Equipment Perspective

July 17, 2012
The IP Multimedia Subsystem (IMS) dates from 3GPP release 5 almost a decade ago, but is now becoming a reality with the rollout of IMS-based LTE networks. IMS enables convergence on multiple fronts, including access types (fixed, mobile), service types, application control functions and convergence between telephony and traditional data delivery. This paper presents a high-level technical view of the IMS architecture as seen by LTEcapable User Equipment (UE).
