HP Introduces W-CDMA Signal-Generation Capability to Aid Development of 3G Base-Station and Mobile Receivers; Solution Successfully Demonstrated at NTT DoCoMo, Japan.PALO ALTO Palo Alto, city, California Palo Alto (păl`ō ăl`tō), city (1990 pop. 55,900), Santa Clara co., W Calif.; inc. 1894. Although primarily residential, Palo Alto has aerospace, electronics, and advanced research industries. , Calif.--(BUSINESS WIRE)--Aug. 28, 1998-- Hewlett-Packard Company today announces new wideband code-domain multiple access (W-CDMA See WCDMA. ) signal-generation capabilities that enable wireless-communications R&D engineers to develop W-CDMA base-station and mobile receivers. W-CDMA is a third-generation (3G) wireless technology designed to deliver higher transport capacity for high-speed data and low-cost voice services than today's wireless networks. With a special option now available for the HP ESG-D series RF signal generators, R&D engineers can accelerate the development of W-CDMA base-station and mobile receivers by fully exercising their receiver to ensure it meets performance requirements. NTT DoCoMo (NTT Mobile Communications Network, Inc., Japan) Founded in 1991, NTT DoCoMo is a spinoff of Japan's NTT (Nippon Telegraph and Telephone Corporation) which provides wireless services, including cellular, paging, satellite and maritime and in-flight telephone services. , a leading mobile-communications operator in Japan, is coordinating the rollout of the first W-CDMA mobile network. On Aug. 18, HP's test solution was demonstrated successfully during the indoor testing phase of the experimental W-CDMA system. "This new W-CDMA signal-generation capability, along with design software and signal-analysis products introduced since April, strengthens HP's suite of solutions for W-CDMA product development," said Duane Hartley, general manager of HP's Microwave Instruments Division. "We will continue to address evolving standards, offering the latest in design tools, test equipment and consulting services to keep pace with 3G technology." IN-CHANNEL, BASE-STATION AND MOBILE-RECEIVER TESTING The new option (H98) provides real-time data Real-time data denotes information that is delivered immediately after collection. There is no delay in the timeliness of the information provided. Some uses of this term confuse it with the term dynamic data. on uplink or downlink signals. For uplink simulation, users can generate a single coded channel DTCH DTCH Dedicated Traffic Channel DTCH Detached Strength or three multicode DTCH channels, for sensitivity-testing needs. For the downlink, users can generate two coded channels (Perch 1 and 2 and DTCH). The user interface of the signal generator lets engineers select symbol rate, long code and short code to assure quick setup of meaningful tests. Typically, better than 63dBc adjacent channel power ratio (ACPR ACPR Adjacent Channel Power Ratio ACPR Ariel Center for Policy Research (Israel) ACPR Adjacent-Channel Power Rejection ACPR Adjacent Channel Protection Ratio ACPR American Crossbred Pony Registry ACPR Advanced Core Performance Reactor ) performance with less than 1.25 percent error vector magnitude The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation points precisely at the ideal locations, however various (EVM EVM Earned Value Management EVM Evaluation Module EVM Error Vector Magnitude EVM Electronic Voting Machine EVM Expert Group on Vitamins and Minerals EVM Economic Value Management EVM Extraneous Vegetable Matter EVM Extra-Value Meal EVM Electronic Voltmeter ) ensures that the signal will meet performance requirements for W-CDMA. Other W-CDMA options now available include Option H97, which provides a multichannel Using two or more paths for transmission or processing. It can refer to a variety of architectures including (1) multiple I/O channels between the CPU and peripheral devices, (2) multiple wires in a cable, (3) multiple "logical" channels within a single wire or fiber or (4) multiple signal with proper long- and short-code spreading and timeslot multiplexing. This option generates a stimulus for component test applications as well as an interfering signal in adjacent channel-selectivity testing. Test setup is quick and easy, with predefined channel configurations, including Perch and 1 to 127 traffic channels (DTCH) at various symbol rates. With the addition of Option H99, adjacent channel power (ACP (Associate Computing Professional) The award for successful completion of an examination in computers offered by the ICCP. It is geared to newcomers in the computing field. For more information, visit www.iccp.org. ACP - Algebra of Communicating Processes ) will be better than -63dBc for one DTCH. To continue to meet testing needs amid evolving standards, the flexible architecture of the HP ESG-D series RF signal generators allows channel coding A way of encoding data in a communications channel that adds patterns of redundancy into the transmission path in order to lower the error rate. Such methods are widely used in wireless communications. See convolutional code and Viterbi decoder. structure to change as commercial standards are developed.
