History of Communication: Communication is a way of expressing your feelings or transmission of information‚ messages to one another by conversation‚ visuals‚ signals‚ script or through activities. Communication can take place between two or more persons and in fact communication is not limited to humans and it takes place between animals and human beings. Communication is always critical to human society. Communication has been playing a key role in human society since the time of evolution

important to know the basic things and the scope of the project you have chosen to do. The following four areas are ideal for EEE students to do the project work. o Digital Signal Processing (DSP) o VLSI o Communication o Embedded Systems Digital Signal Processing (DSP) is about processing of the digital and audio signals using MATLAB software. VLSI involves VLSI designs of new ICs implemented from Altera & Xilinx. The projects can be on electrical communication‚ machine control etc. Communication

tsinghua.edu.cn Abstract—Tracking dynamics on the GPS signal is still a big challenge to the receiver designer as the operating conditions are becoming more volatile. Usually‚ the Phase-locked loop (PLL) is used in GPS receivers to track an incoming signal and to provide accurate carrier phase measurements. However‚ in high dynamic situations‚ the conflict between improving PLL tracking performance and the ability to track the signal necessitates some compromises in PLL design. Optimizing

ANALOGUE & DIGITAL SIGNALS Name: - BHAVESH PATWAL Tutor : - JAY PATEL Date: - 20th November‚ 2012 I . Analogue Signals : - Analogue signal is a form of transmitting data such as voice‚ image or video using continuous signals. This is a relatively inexpensive way to transmit data. Analogue communications are usually sent via twisted cables or fibre optic cables and they are transmitted via a carrier signal which is set at a specific frequency. The primary disadvantage of

involved. We propose a new video data hiding method that makes use of erasure correction capa- bility of repeat accumulate codes and superiority of forbidden zone data hiding. Selective embedding is utilized in the proposed method to determine host signal samples suitable for data hiding. This method also contains a temporal synchronization scheme in order to withstand frame drop and insert attacks. The proposed framework is tested by typical broadcast material against MPEG- 2‚ H.264 compression‚

CHAPTER 2 MULTIPLE ACCESS A limited amount of bandwidth is allocated for wireless services. A wireless system is required to accommodate as many users as possible by effectively sharing the limited bandwidth. Therefore‚ in the field of communications‚ the term multiple access could be defined as a means of allowing multiple users to simultaneously share the finite bandwidth with least possible degradation in the performance of the system. There are several techniques how multiple accessing can
