چکیده
DSSS (Direct Sequence Spread Spectrum) is one of the main technique of spread spectrum system and is the most common version use for military communication. In this paper, I have designed and implemented RADAR (Radio Wave Detection and Ranging) transmitter and receiver using direct sequence spread spectrum for range estimation. Most challenging part in RADAR system is to be getting better accuracy and resolution. In this paper, we mainly concentrates on direct sequence spread spectrum because it has some inherent merits like accuracy of ranging, sensitivity of power estimation, interference suppression than other types of spread spectrum. MATLAB simulink tool is used for designing and simulating of RADAR transreceiver using DSSS to obtain parameter and to test the influence of the signals on the system.

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

متن کاملDirect Sequence Spread Spectrum with Barker Code and QPSK
Spread Spectrum technique is a digital passband technique. It uses a special code which is known only to the transmitter and receiver of that message. The special code appears as a noise signal to the jammer who tries to jam the channel. In this paper, we present the Direct Sequence Spread Spectrum. Firstly, we show an overview of Direct Sequence Spread Spectrum, then, we simulate Direct Sequen...
متن کاملDesign and Implementation of DSSS-CDMA Transmitter and Receiver for Reconfigurable Links Using FPGA
Direct sequence spread Spectrum (DSSS), is also called as direct sequence code division multiplexing (DS-CDMA). In direct sequence spread spectrum, the stream of information to be transmitted is divided into small pieces, each of which is allocated across to a frequency channel across the spectrum. A data signal at the point of transmission is combined with a higher data-rate bit sequence (also...
