Capacity Analysis of EMNC System in an Interference Limited Scenario

EM based Nano Communication is a new paradigm of communication system which involves Bio-Nano-Machines (BNMs) for information exchange. Numerous BNMs are required to implant inside the body at different locations to monitor different diseases. Desired information from each of the nano-transmitters is routed via nano-routers. This makes the system interference limited scenario. In this manuscript different adaptive capacities are proposed over interference limited scenarios under dual Selection Combining (SC) diversity. In particular, analytical expressions for capacity under two types of adaptive schemes are presented. One of them is Capacity under Optimal Rate Adaptation (CORA) keeping the power constant whereas, second is Capacity under Channel Inversion with Fixed Rate(CCIFR). It is observed that simulated results show perfect agreement with the theoretical background.
