“…It can usually cover more 52 communications scenarios encountered in real mobile wireless 53 systems, compared with the other composite channel models. 54 Furthermore, the K G channel model often results in closed- 55 form solutions when applied for system performance analysis 56 [4]- [6]. Therefore, in this paper, we are interested in analyzing 57 the performance of multihop links when they are operated in 58 wireless channels characterized by the K G channel model.…”

“…The shadowing effect is assumed to be follow a log-normal distribution, to which a Gamma fading distribution is an alternative approximately [30] for simplifying calculation. The multipath fading is assumed to be follow a Nakagami-m distribution which spans via the m parameter the widest range of the amount of fading (from 0 to 2) among all the multi-path distributions [31].…”

It is important to assess the effect of transmit power allocation schemes on the energy consumption on random cellular networks. The energy efficiency of 5G green cellular networks with average and water-filling power allocation schemes is studied in this paper. Based on the proposed interference and achievable rate model, an energy efficiency model is proposed for MIMO random cellular networks. Furthermore, the energy efficiency with average and water-filling power allocation schemes are presented, respectively. Numerical results indicate that the maximum limits of energy efficiency are always there for MIMO random cellular networks with different intensity ratios of mobile stations (MSs) to base stations (BSs) and channel conditions. Compared with the average power allocation scheme, the water-filling scheme is shown to improve the energy efficiency of MIMO random cellular networks when channel state information (CSI) is attainable for both transmitters and receivers.

Abstract-A new packet-selection based transmission scheme is proposed on a dual-hop link with buffer aided amplify-andforward relay, where the relay with a buffer can record the channel information of source-relay hop and store the received packets. In order to satisfy the constraint of equivalent end-to-end SNR, the relay may pick up a packet in the buffer to transmit, with consideration of the channel statuses of both the source-relay hop and the relay-destination hop. Therefore, by adjusting the packet transmission order in the relay, the outage probability can be decreased in the proposed transmission scheme. Both theoretical analyses and simulation results show that the proposed scheme outperforms traditional ones by a significant margin of 2-4 dB gain in terms of outage probability.
