Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ultra wide-band is based on transmission with very short pulses of low energy.The wider bandwidth of UWB technology has several advantages such as excellent penetration ability, multi-user support and high channel capacity.UWB poses design challenges for low power and low complex systems at wider bandwidth.For digital systems,it also requires high sampling rate and intensive computation to estimate gain and delay of multi path channel. The performance of non-coherent transmitted reference (TR),frequency-shifted reference (FSR) and code- shifted reference (CSR) systems are compared with the orthogonal Gold code (OG) code reference (CR) systems for single and multiuser for low data rates. First,the performance of non-coherent receivers for single-user system working in residential LOS is evaluated.Secondly,the performance comparison of TR, FSR, CSR and OG-CR are presented in multiuser environment. The simulation results validate that CSR and OG-CR have better performance than TR and FSR in multiuser environment. Finally,results show that CSR shows better performance than OG-CR for few users and almost same performance as OG-CR at high SNR with more number of users. 72 pp. Englisch.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This dissertation mainly deals with the communication in both Single and Multi user environment. On usage is carried out this simulation of Wireless LAN, which highlights various aspects that happen in communication when more than one user gets involved. Bluetooth, IEEE802.11 standard uses these models to enable different usage models from networking to cable replacement. Implementation of these usage models and issues specific to Bluetooth protocol and IEEE802.11 protocol stack embedded into operating systems framework in order to ensure seamless integration. Simulation of the situation is using MATLAB software. In the centuries, communication was basically wired communication with the advent of Electromagnetic waves and different Modulation Techniques it shifted to wireless environment. The introduction of various digital techniques has made communication predominantly digital. These days computers are being widely used to process digital data. Today, Communication enters our daily lives in so many different ways that it is easy to overlook the multitude of its facets.

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book basically deals with the pseudo codes used in spread spectrum communication system. This includes the various types of pn codes and their techniques, benefits and shortcomings and as well as their properties. It has been seen that the length of the code, autocorrelation and cross correlation properties can be used to determine the best suitable code for any particular communication environment. Therefore, the code with suitable autocorrelation properties along with low cross correlation values was tried to find out. It was assumed only the bipolar case. At first, the best codes in 31 bit codewords which have the best auto-correlation properties were discovered. Then the work was concentrate on Walsh-Hadamard code. The Walsh-Hadamard code has the best cross correlation properties but it lacks self-synchronization feature. It was also tried to find out those codes in 64 Walsh-Hadamard codes which have best auto correlation properties. Finally the barker codes were analyzed. The barker code has good auto- correlation properties and the pair with the low cross correlation was discovered so that they can be used in multi-user CDMA environment.
