The Gray Watson debugging malloc library is C source code for a drop in replacement for the system malloc & other memory manage ment routines. What is unique about this library is that it contains a number of powerful debugging facilities including very comprehensive heap testing and ex- cellent run-time debugging information.
Models UWB TX and RX using BPSK fifth derivative.
MATLAB Release: R13
Description: This m file models a UWB system using BPSK with the fifth order derivative of the gaussian pulse with correlation receiver and intgrator.
This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations for the Gaussian pulse waveforms. The first derivative is considered to be the monocycle or monopulse as discussed in most papers. The second derivative is the waveform generated from a dipole antenna used in a UWB system. Other information is contained in the file.
This software designs the document management system may replace the tedious low effect the manual management, has used the c language programming, realized the document input to loan, the information management and the data compilation three big cores function
This m file analyzes a coherent binary phase shift keyed(BPSK) and a amplitude shift keyed(ASK) communication system. The receiver uses a correlator(mixer-integrator[LPF]) configuration with BER measurements comparing measured and theoretical results. The bandpass and low pass used in the receiver are constructed using z transforms.
This a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory.
Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is
"runsim.m". In these simulations the SISO option is not explicitly given. This is because the SISO result for a particular
type of modulation is shown in every plot for purposes of comparison.
This software has been tested on MATLAB version 6.0 and above with signal processing and communication toolbox options.
The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding
by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been
implemented for a 2x2 system. The reader can program other variations.
The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
I want to provide an example file system driver for Windows NT/2000/XP. For some time I have worked on an implementation of RomFs. RomFs is a small filesystem originally implemented in Linux, because of its simple disk layout its a good choice for an example driver. The current status is a working read-only driver that supports caching of file data, the create functionallity still needs some work but I m releasing it due to the high public demand.
Very very small GUI. Usefull for small system,
without OS or small OS. Event driven, support user message to GUI.
included simle widgets: nested menu, window, dialog, inputline, scroll list.
Footprint for 16 bit CPU - aprox. 60kB.
Languadge - C
