Abstract:
One of the major drawbacks for wireless communication systems in Manhattan 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
pr
esented to suggest an efficient inter-sector cooperative transmission strategy in Manhattan environment.
