Performance analysis of SSK modulation using multipath with multihop DF relay over Nakagami-m fading channel

The data transfer between devices should be prominent in the 5G and Beyond 5G communication systems. Wireless communication system needs a sophisticated communication setup with less hardware and complexity. In this paper, Space Shift Keying (SSK) modulation is considered to be a convenient scheme for multi antenna system by activating a single antenna at one time. Moreover, Cooperative communication has more reliability in point-to-point communication by the relaying system. So, inclusion of SSK in cooperative communication system will lead to best performance in terms of data transmission. Thus, end-to-end Bit Error Rate (BER) in the multi-hop multi-branch DF relaying (MMDFR) model under cooperative communication scenario using SSK modulation scheme is analyzed. The closed-form expression for BER is derived over Nakagami-m fading channels and the results are verified with Monte Carlo simulation. This proposed model can also be compared with existing models which includes SSK modulation schemes. This system may be useful in IoT applications for 5G to improve network coverage, user experience and system capacity.
