电子书籍 A combined space鈥搕ime block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-m
A combined space鈥搕ime block coding (STBC) and eigen-space tracking
(EST) scheme in multiple-input-multiple-output systems is
proposed. It is proved that the STBC-EST is capable of shifting
hardware complexity from the receiver to the transmitter without
any bit error rate (BER) performance loss. A ...

A Design and Implementation of The Online Shopping System
Abstract: Along with the development of the computer ,the database technique is widespread in the application of Internet, more and more , providing more thoughtful and humanized service for the large network customer. Characteristic serv ...
技术资料 TE 0.6毫米中心距高速CHAMP扩展坞系列连接器
The docking connector series is designed for high density,low profile(3.8mm)shielded applications featuring two rows of contacts on 0.6mm pitch centerlines.Contacts on a 0.6mm centerline can save 30% of linear board space,while the 3.8mm low profile housing reduces connector height by approximately ...

This paper examines the asymptotic (large sample) performance
of a family of non-data aided feedforward (NDA FF) nonlinear
least-squares (NLS) type carrier frequency estimators for burst-mode
phase shift keying (PSK) modulations transmitted through AWGN and
flat Ricean-fading channels. The asymptoti ...
电源技术 跟踪和排序功能的紧凑型双通道降压转换器
 
Typical industrial and automotive applications requiremultiple high current, low voltage power supply solutionsto drive everything from disc drives to microprocessors.For many of these applications, particularly thosethat have size constraints, the LT3501® dual step-downconverter is a ...

This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 &micro m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the sync ...

测试测量 LT5528 WCDMA ACPR和AltCPR测量
 
ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. T ...

Aiming at the application of passive trackinn based on sensor array, a new passive trackinn usinn sensor array
based on particle filter was proposed. Firstly, the“fake points" could be almost entirely and exactly deleted with the aids of the
sensor array at the expense of an additional sensor. Seco ...

What I am trying to introduce here is a full fledged Java Instant messenger, which has all the features supplied by commercial messengers like Yahoo or MSN. Although it cannot compared to be in par with those messengers, it is an attempt by me to learn Advanced Java and JNI concepts. The challenges ...
