Wireless alarm with decision making based on MC-CDMA on FPGA platform

Abstract

These days, security takes up a high priority in the world of businesses and enterprises, as well as inside homes where families and assets are valuable and need to be protected. The purpose of this project is to implement a new top of the line wireless security system that is easy on the eyes and is most certainly efficient to keep burglars and unwanted intruders away from people's properties. A Field Programmable Gate Array FPGA implementation of a new algorithm for intrusion detection using CDMA over a common channel is presented is this literature. A creation of the algorithm was made using VHDL language, and a simulation was held on FPGA dedicated software that permitted the illustration of the results as a relationship between the input and the output; the input being the reactions of the intruder detection equipment sent over the common wireless channel and the output being exactly the same signals that were transmitted, giving a control center the ability to react accordingly and set off the alarm in case of an intrusion. Performance analysis of the system was done using the output waveforms and special calculation algorithms calculated the probability of error: more errors occurred when inappropriate codes were used and also when the number of detection equipment increased. It is suggested that the implementer of the system uses appropriate codes and optimizes the amount of motion sensors inside his facility. The result suggests that this is a well-performing alarm system and encourages users to implement this system in their facilities or homes to secure their assets.
