Cooperation strategies for multi-user transmission in manhattan environment

초록

One of the major drawbacks for wireless communication systems inManhattan environment with tall buildings lining both sides of the streets is the performance degradation caused by the penetration loss and the effects of inter-sector interference. To overcome such a degradation, cooperation among the sectors is under an active investigation as an efficient means to provide an enhanced coverage as well as increased spectral efficiency. In this paper, we describe various type of cooperation sector location for cooperative multi-user transmission, and determine cooperation strategies for the cooperative operation among sectors by evaluating and comparing the types of microcell in Manhattan environment. The results shows that the more suitable number of cooperation sectors is determined by signal-to-interference plus noise ratio (SINR), outage probability, and throughput comparison. Performance variations based on different numbers of sector density under cooperation are also presented to suggest an efficient inter-sector cooperative transmission strategy in Manhattan environment.
