Performance Evaluation of Different Modulation Schemes for Ultra Wide Band Systems

Performance evaluation of OOK and BPSK modulation schemes for IR-UWB receiver using wide band LNA

Ultra wide band systems are considered as one of the most exciting technologies due to its capability of transmitting data over a wide frequency spectrum with very low power and high data rates. In any UWB receiver the low noise amplifier is the first stage. The LNA plays a crucial role in the whole reception chain. In this paper, we examine the performance of two different modulations techniqu...

Performance evaluation and comparison of different modulation schemes for UWB multiaccess systems

Ultra wideband system performance is analyzed in terms of error probability for different modulation and multiaccess schemes over the AWGN channel. The analysis leads to closed-form expressions of the bit error probability under the hypothesis of chip-synchronous systems, allowing a comparison of different techniques in a possible scenario for UWB applications. The use of convolutional codes to...

Performance Evaluation of LTE Network with Different Modulation Schemes

Long Term Evolution (LTE) is the latest step towards the 4th generation of cellular networks. This revolution is necessitated by the increase in demand for high-speed connection on LTE networks .The speed of any network depends of its throughput. In this paper we described how the throughput calculated and how the throughput affected by parameter such as bandwidth of channel, types of modulatio...

A survey on ultra wide band medium access control schemes

Ultra wideband (UWB) technology based primarily on the impulse radio paradigm has a huge potential for revolutionizing the world of digital communications especially wireless communications. UWB provides the integrated capabilities of data communications, advanced radar and precision tracking, location, imperceptibility and low power operation. It is therefore ideally suited for the development...
