Hybrid Communication System using MIMO - OFDM
The enormous growth for Wireless broadband services and huge take up of mobile technology demands for higher data rate services.For a communication network to be successful only provisioning of high data rates alone is not sufficient, but also should provide wide coverage.Both satellite and terrestrial networks cannot guarantee this on their own. This incapability is attributed to capacity of c...
متن کاملMultiband-OFDM Based Ultra-Wideband Communication System
This paper investigates the Multi-bandOFDM (MB-OFDM) based Ultra-Wideband for working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHYlayer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un coded bit error rate (BER) of MB-OFDM over the fadin...
متن کاملHigh-speed Power Line Communication System based on Wavelet OFDM
Recently, the demand of high-speed network in home is increasing. PLC (Power Line Communication) is expected as one method of realizing it. OFDM is one of the methods, which realizes high-speed PLC. But the minimum stopband attenuation of OFDM modulation is only -13dB. It indicates that OFDM subchannels are not spectrally isolated, therefore OFDM is sensitive to the locations of narrow band int...
متن کاملA Multi-Robot System Based on A Hybrid Communication Approach
Communication plays an important role in a multi-robot system. In a large system with many robots, it is difficult for all robots to exchange information at a time because of their limited communication capacities. On the other hand, sometimes there is such a situation where no explicit communication is allowed between robots. Therefore, efficient and reliable communication together with non-ex...
متن کاملHybrid Wireless Communication System Based on Arm9 for Coalmine Monitoring
The most important aspect of the MINER Act is providing reliable communication for miners before and after tragic accidents. Reliable communication has always been a challenge in underground mines due to changing topologies and harsh environment. In addition, disasters disable electricity and communications cables, block tunnels and cause fire. These may damage the communication infrastructure ...
