SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The signals with spread spectrum of direct sequence type BPSK (BPSK-DS-SS) -The signals with spread spectrum of direct sequence type QPSK – DS–SS - Frequency hopping spread spectrum signals (FH-SS)

C++ by Dissection presents a thorough introduction to the programming process by carefully developing working programs to illuminate key features of the C++ programming language. Program code is explained in an easy-to-follow, careful manner throughout. The code has been tested on several platforms and is found on the bundled CDrom accompanying this text. The code in C++ By Dissection can be used with most C++ systems, including those found in operating systems such as MacOS, MS-DOS, OS/2, UNIX, and Windows.

Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.

This code outputs various NMEA strings to a com port. The code was originally used to test naviation programmes. First select the required com port and the required NMEA message string. There is a default starting position but this can be changed to suit just by typing in a new position. Click on the Start button the current position displayed will change according to the speed and heading selected and the selected NMEA string will be output to the com port and will reflect the current position as displayed. There is a text box which is normally not visible. If you change this to visible the relevant NMEA string can be displayed.
