In this paper, we present an analytical framework to derive the performance\nof a molecular communication system where a transmitter bio-nano-machine (TBN)\nis communicating with a fully-absorbing spherical receiver bio-nano-machine\n(RBN) in a diffusive propagation medium in the presence of other TBNs. We\nassume that transmit bits at each TBN is random and different than transmit\nbits at other TBNs. We model the TBNs using a marked Poisson point process\n(PPP) with their locations as points of PPP and transmit symbols as marks. We\nconsider both inter-symbol interference (ISI) and co-channel interference\n(CCI). ISI is caused by molecules transmitted in the previous slots while CCI\nis due to the molecules emitted from other TBNs. We derive the bit error\nprobability of this system by averaging over the distribution of the transmit\nbits as opposed to the past approaches consisting of conditioning on previous\ntransmit bits and/or assuming the transmit bits of every TBN are the same.\nUsing numerical results, we validate our analysis and provide various design\ninsights about the system, for example, the impact of detection threshold on\nthe system performance. We also show the importance of accurately incorporating\nthe randomness of transmit bits in the analysis.\n
