A unique length measurement method, called the multiple pulse train interference-based time-of-flight (TOF) method, is proposed and demonstrated for the first time. By taking advantage of both the high-accuracy measurement capability of a pulse train interference method and the arbitrary and absolute length measurement capability of a TOF method, the present method is expected to be useful for ...

Industry communications systems without thread has grown tremendous over the last few years, these systems have evolved significantly in terms of services offered, the wireless communication suffers of the Multiple Access Interference (MAI) and computational complexity. We propose a new technique of coding applies to the downlink of Multi input Multi output MultiCarrier Code Division Multiple A...

Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

The heterogeneous network (HetNet), which deploys small cells such as picocells, femotcells, and relay nodes within macrocell, is regarded as a cost-efficient and energy-efficient approach to resolve increasing demand for data bandwidth and thus has received a lot of attention from research and industry. Since small cells share the same licensed spectrum with macrocells, concurrent transmission...

Successive interference cancellation (SIC) is a promising practical scheme for increasing the capacity of CDMA systems. The interference cancellation is never perfect, and the residual cancellation errors propagate because of the successive nature of the decoding. In fact, these residual errors are the principle capacity-limiting issue in SIC systems. Until now, the statistics of these errors h...

To satisfy the ever-increasing data rate and service coverage demands, wireless communication networks evolve into heterogeneous networks (HetNets), where low-cost small base stations are embedded in conventional macrocells. Intercell interference emerges as the key capacity-limiting factor in such dense networks, restricting the reusability of spectral resources. Therefore, advanced interferen...

The influence of microwave oven interference on IEEE802.11 Wireless Local Area Network (WLAN) performance is a significant factor because they share common spectrum in the 2.400 2.4835 GHz Industry, Science, and Medicine (ISM) band. FCC regulations permit radiated power of up to 1 watt in this band provided spread spectrum techniques are employed. Spread spectrum methods facilitate multiple use...
