Abstract: In view of expense of extra redundancy and reduced spectral efficiency, prefix based multicarrier transmission can find its major applications in 5G and beyond 5G wireless communication networks with properly designed low complexity signal detection technique. Hybrid prefixing aided multicarrier modulated system is capable of providing reasonably a... Show More

Abstract: A large number of small cells are deployed in a traditional heterogeneous network to form an ultra-dense network. The ultra-dense network effectively increases the capacity of the network, but also introduces serious interference problems between low-power nodes. In order to solve the problem of downlink interference existing in the ultra-dense net... Show More

Abstract: Optical wireless (OW) that is also known as free space optical (FSO) communication system are impaired by adverse weather conditions, such as rain, fog, cloud, snow and atmospheric turbulences. To reduce the destructive effect of atmospheric turbulence, OFDM technique itself have already been reported in several publications which is not sufficient... Show More
