锁相回路可视为一个输出相位和输入相位的回授系统用以同步输入参考讯号和回授后输出信号。并让其操作同样的频率。如(图一)所示,简单锁相回路[3,4]是由三个电路构成,分别为相位侦测器(Phase Detector)、回路滤波器(Loop Filter)、压控荡器(VCO)

A new blind adaptive multiuser detection scheme based on a hybrid of Kalman filter and subspace estimation is proposed. It is shown that the detector can be expressed as an anchored signal in the signal subspace and the coefficients can be estimated by the Kalman filter using only the signature waveform and the timing of the desired user.

It may analyze the window structure, the advancement and the window news, has the very greatly auxiliary function to the development work. When we need to study some object, so long as assigns out its search window, drives the detector the indicator to assign the window/to control on to release then. Under, the author on and everybody same place, makes with VC to belong to own Spy++.

This book shows how to design and implement C++ software that is more effective: more likely to behave correctly more robust in the face of exceptions more efficient more portable makes better use of language features adapts to change more gracefully works better in a mixed-language environment is easier to use correctly is harder to use incorrectly. In short, software that s just better.

Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform

This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmitter. The fractional-N synthesizer forming the basis of the transmitter uses a combined phasefrequency detector (PFD) and digital-to-analog converter (DAC) circuit element to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.
