    In communication systems channel poses an important role. channels can convolve many different kind of distortions to our information. In perticular wireless channels multipath distortion is sevear. and more sevear is such distortion is random. To handle this, multipath affected channels require Equalizers at receaver end. such equalizer uses different learning Algorithms for identifying channels continuously. This project is VHDL implementation of LMS learning algorithm with pipelined architecture. so this implementation can work with higher data rates with less clock speed requirments and so with less power consumpiton It uses Fixed point arithmatic blocks for filtering so suitable for coustom asic.

    The emphasis of this book is on real-time application of Synopsys tools, used to combat various problems seen at VDSM geometries. Readers will be exposed to an effective design methodology for handling complex, submicron ASIC designs. Significance is placed on HDL coding styles, synthesis and optimization, dynamic simulation, formal verification, DFT scan insertion, links to layout, physical synthesis, and static timing analysis. At each step, problems related to each phase of the design flow are identified, with solutions and work-around described in detail. In addition, crucial issues related to layout, which includes clock tree synthesis and back-end integration (links to layout) are also discussed at length. Furthermore, the book contains in-depth discussions on the basics of Synopsys technology libraries and HDL coding styles, targeted towards optimal synthesis solution.

    The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its customers with both voice and comprehensive data services. With an i-mode phone, users can exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible Internet sites. The i-mode phone contains a browser that displays i-mode compatible HTML web pages. Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode browser. You can also use the phones’ My Picture and Standby Screen applications to view Flash Lite movies. Although a number of manufacturers produce 505i phones, all of them support the same Flash Lite functionality.

    P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05, and 0.1 sec intervals to obtain x(n). b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation (use ∆ t = 0.001) and determine the frequency in ya (t) from your plot. (Ignore the end effects.) C) Reconstruct the analog signal ya (t) from the samples x (n) using the cubic spline interpolation and determine the frequency in ya (t) from your plot. (Ignore the end effects.)

    A Public Key Infrastructure (PKI) binds cryptographic public keys to physical entities through digital certificates. A PKI includes components that issue digital certificates and distribute certificate status information. PKI users select one or more certificate issuers as trust anchors, and establish security services based on certificates that may be validated using one of their trust anchors.
