Application Note: Linking RF Design and Test through AWR Software and LabVIEW

AWR has a new application note that explains how EDA tool integration benefits designers of circuits for 3G and 4G wireless systems. The app note describes the benefits of using AWR’s Microwave Office and Visual System Simulator (VSS) high-frequency design software with National Instruments’ LabVIEW signal processing software and virtual instruments. The title of the paper is Using LabVIEW in the AWR Design Environment To Design Complex Circuits for Wireless Applications.

Cognitive Baseband Radio Architecture for 4G and Concurrent Streams

Imec announced a cognitive baseband radio (COBRA) architecture for 4G applications requiring up to 1Gbit/s throughput and multiple asynchronous concurrent streams (such as simultaneous digital broadcasting reception and high-speed internet access). COBRA is a low-cost, flexible architecture that is ideal for wireless communication where terminals give users ubiquitous broadband access to a multitude of services.

Tensilica ConnX BBE16 BaseBand Engine DSP

The ConnX BBE16, from Tensilica, is a second generation baseband engine for LTE (long-term evolution) and 4G baseband SOC (system-on-chip) designs. The ConnX BBE16 is an ultra-high performance 16-MAC fixed-point DSP engine. It is based on an 8-way SIMD (Single Instruction, Multiple Data), 3-issue VLIW (Very Long Instruction Word) architecture with two 128-bit load/store units. It is a click-box configuration option with the configurable Xtensa LX3 processor core. Designers can also choose from a number of other configuration options (memories, interfaces, etc.) when designing their core. The ConnX BBE16 and an evaluation kit will be available in the second quarter of 2010.

The Five Pitfalls of 4G Baseband SoC Design Webinar

Tensilica is offering a webinar on the the five pitfalls of 4G baseband SOC design. The webcast will take place on Tuesday, October 27, 2009 at 11 am PT (2 pm ET). The webinar explores five significant challenges faced by designers of efficient digital basebands, including pitfalls in LTE’s many modes, excessive cost and power, the “million MIPS” hurdle of Turbo decoding, and the dilemma of choosing the right communications among the LTE building blocks. The online seminar uses detailed examples from an end-to-end LTE PHY baseband architecture to highlight the key dos and don’ts.
