Coherent joint-processing CoMP in pico-cellular lamp-post street deployment

Abstract

In this paper we study the performance of coherent joint-processing coordinated multi-point (CoMP) transmission, also known as Network MIMO, in pico-cellular street deployments with lamp-post base station installation. Previously published and experimentally confirmed short-range wireless propagation models have been applied. The performance is compared against the equivalent case of macro-cellular deployment. In both deployments, we report significant Network MIMO gains compared to the conventional solution without coordination. Effects of the base station antenna elevation and transmit power are also analyzed. Greater benefit of Network MIMO is determined in pico- than in macro-cellular systems.
