The software is capable to simulate space time code [1] for QPSK modulation using different number of state. Examples of generator matrix up to 256 stetes are provided. Variable signal to noise ratio (SNR) might be applied to produce bit error rate (BER) or frame error rate (FER) curves.

Huffman codes In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0’s and 1’s? To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. This problem can by solved by using an extended binary tree which is used in the 2- way merging problem.

Custom Visual Basic Packager and Installer for Visual Basic Developers. This is a group of standard exe projects 1. Packager 2. Setup1 The packager works like Visual basic Application deployment Wizard. And the setup1 project is used for the installation of the package. This project demonstrates how to compile visual basic project without launching the Vb6 kit and retrieving the dependency Files of any Visual basic project (although roughly done without any specific algorithm), Somebody can help me with this. I don’ t have time for the project, so I don’ t want any comment on the code indentation or arrangement and variable scoping. Comments are in the code therefore it would not be a problem to understand the code. If anyone wants to vote, I will like it Oh! I found some of the setup1 code and modify it with new features, so i have no or less credit for the setup1 project I felt like sharing code with PSCites. Thats why I made it

This is GPS Acquisition..by Matlab, this file performs cold start acquisition on the collected "data". It searches for GPS signals of all satellites, which are listed in field "acqSatelliteList" in the settings structure. Function saves code phase and frequency of the detected signals in the "acqResults" structure.

Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

RFID, the wireless technology that has helped millions of people around the world to protect their property and make their workplaces safer is now in danger of being viewed as a security risk. Ray Stanton examines the love-hate relationship between people and Radio Frequency Identification [RFID] tags and highlights the need for informed debate about the privacy issues the technology raises.

The Window Design Method The basic idea behind the design of linear-phase FIR filters using the window method is to choose a proper ideal frequency-selective filter [which always has a noncausal, infinite duration impulse response] and then truncate its impulse response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the impulse response of the ideal filter a time window w[n] is used. Available windows in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning
