“…In this system, the normal cyclic prefix is replaced with a group of zeros and added after the block of data, which acts as the cycle prefix for the next data block [149] [150]. SC has lower PAPR compared to OFDM and therefore has been used by the IEE802.11ad standard for reliable transmission [151]. IEE802.11ad and IEEE 802.15.3c also use OFDM to combat ISI in frequency-selective fading in the 60 GHz band to achieve multi Gbps data rates over short distances [152].…”

“…Furthermore, DAC/ADC sampling processing needs to process wide band signals in mm-wave, which results in considerable power consumption. In [151], the authors have proposed a power-efficient subsampling system to improve OFDM performance for mm-wave communications. The proposed OFDM with a low resolution ADC architecture has shown a power consumption reduction in the 60GHz band.…”

In order to meet the huge growth in global mobile data traffic in 2020 and beyond, the development of the 5 th Generation (5G) system is required as the current 4G system is expected to fall short of the provision needed for such growth. 5G is anticipated to use a higher carrier frequency in the millimetre wave (mm-wave) band, within the 20 to 90 GHz, due to the availability of a vast amount of unexploited bandwidth. It is a revolutionary step to use these bands because of their different propagation characteristics, severe atmospheric attenuation, and hardware constraints. In this paper, we carry out a survey of 5G research contributions and proposed design architectures based on mm-wave communications. We present and discuss the use of mm-wave as indoor and outdoor mobile access, as a wireless backhaul solution, and as a key enabler for higher order sectorisation. Wireless standards such as IEE802.11ad, which are operating in mm-wave band have been presented. These standards have been designed for short range, ultra high data throughput systemS in the 60GHz band. Furthermore, this survey provides new insights regarding relevant and open issues in adopting mm-wave for 5G networks. This includes increased handoff rate and interference in Ultra-Dense Network (UDN), waveform consideration with higher spectral efficiency, and supporting spatial multiplexing in mm-wave line of site. This survey also introduces a distributed base station architecture in mm-wave as an approach to address increased handoff rate in UDN, and to provide an alternative way for network densification in a time and cost effective manner.

“…One of the methods used to transmit data is the multi carrier modulation a technique used to achieve high data transfer, increase spectral efficiency and reduce error by dividing it into several components. To improve and achieve the highest rates of data transfer, researchers [5][6][7], have developed multi carrier modulation techniques which UFMC, Orthogonal frequency Division Multiplexing (OFDM) [8] and Filter-Bank Based Multi-Carrier (FBMC) are some of the technologies developed. In FBMC system the subcarriers are filtered individually, strongly strengthen the durability inter-carrier interference (ICI) effects.…”
