Model Based on Matern Process for ICI Mitigation in Multi Cell Cooperation

摘要

Ever increasing need of data rate and coverage can be achieved by mitigating the impairments of wireless communication system. Inter cell interference (ICI) is one of the most challenging impairment of wireless communication. To mitigate ICI, multi cell cooperation (MCC) based technique has been proposed in literature. In this paper, ICI mitigation is achieved by using Matérn Hard-Core Point Process (MHCP) instead of Poisson point process (PPP). In MHCP a minimum distance between base stations is maintained. Therefore, MHCP corresponds to real deployment scenario. Also, use of MHCP reduces the analytical complexity significantly compared to that of PPP. A closed form expression for complementary cumulative distribution function (CCDF) of signal-to-interference ratio is derived using MHCP for MCC based system in terms of number of base stations, number of antennas and path loss. Using derived expression of CCDF, analytical expressions for probability density function and ergodic capacity is also presented in the closed form. Finally, performance analysis is shown in terms of ergodic capacity. Results are validated by comparing the proposed results with [4].
