Channel Impairment Analysis in Nano Communication Under CM-3 Scenario

Nano Communication (NC) is evolving as a new paradigm of Wireless Communication (WC) whose application ranges from security to medical, information communication to bioinformatics and body machine interface to consumer industry. But like any other WC system channel modelling of NC has been found as most challenging issue. Channel Model-3 (CM-3) is one of the channel models for NC among others (CM-1 to CM-4). However, in CM-3 model Poisson distribution has been used to estimate the path arrival time and number of arrival paths, for the calculation of channel impulse response (CIR) which is not suitable in real scenario. Therefore, in this paper CIR for NC under CM-3 has been presented using Negative Binomial distribution in place of Poisson distribution. Numerical discussions show the comparison of CIR under given distributions.
