The Performance Investigation of Cooperative Multicast with CP Combining in Hexagonal Network and Small Cell Network

Abstract— With the rapid development of broadband mobile data services, small cell networks are more and more popular to enable high capacity wireless access. Unplanned small cells network, which is described as random network (RN), brings new characteristic different with conventional hexagonal network (HN). This paper mainly investigated the performance of cooperative multicast in HN and RN respectively, where CP combining signal processing is employed. The tractable expressions about the coverage and signal to noise ratio (SNR) distribution of cooperative multicast are derived. It is illustrated by analyses great gain is obtained through cooperation in both HN and RN and the BS power needed to ensure 95% coverage reduced by about 30% when only two BSs are employed to cooperative multicast. Since, given the same BS transmission power and BS distribution density, HN will be energy efficient than RN. Therefore a larger number of BSs with low transmission power should be deployed in RN so that it is possible to be energy efficient as HN.
