GSM (Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for mobile phones in the world. Its promoter, the GSM Association, estimates that 80 of the global mobile market uses the standard.[1] GSM is used by over 3 billion people across more than 212 countries and territories.[2][3] Its ubiquity makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world

I originally wrote this for a Z80 back in the early 80s. I found the source code recently in one of the boxes of printouts I ve kept over the years. Good thing too, since most of the work was on a CPM system using 128k 8inch floppies.

The main function of the traffic detection system is to examine the speed, the flow, the vehicle type and the lane occupancy of the motor vehicles. The method based on ARM embedded system in this paper provides a new means for the traffic detection system research.

In this work an implementation of a geometric nonlinear controller for chaos synchronization in a Field Programmable Gate Array (FPGA) is presented. The Lorenz chaotic system is used to show the implementation of chaos synchronization via nonlinear controller implemented in a Xilinx FPGA Virtex-II 2v2000ft896-4. The main idea is to design a nonlinear geometric controller which synchronizes a slave Lorenz system to a master system and then implement them into the FPGA.

In this paper, a new method is introduced to implement chaotic generators based on the Henon map and Lorenz chaotic generators given by the state equations using the Field Programmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic generators. The new method is based on the MATLAB® Software, Xilinx System Generator, Xilinx Alliance tools and Synplicity Synplify.

In this paper, the feasibility of replacing a chaos source by an equivalent digital pseudo-random generator realized using Linear Feedback Shift Register (LFSR) is studied. Particular emphasis is given on the digital implementation Piece-Wise Linear Affine Maps (PWAM). As an application, an FPGA implementation of four different maps has been experimentally verified in a FM-DCSK test radio system.

In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and the outputs of the correlators are combined with a maximal-ratio combiner. This type of signaling has the desirable properties of exhibiting a narrowband interference suppression effect, along with robustness to fading, without requiring the use of either an explicit RAKE structure or an interference suppression filter.
