Fiber-connected distributed antenna systems (DAS) have been recognized as an effective means to accommodate the coverage and capacity demands of future heterogeneous networks (HetNet). Among various opportunities realized by the architecture, our focus in this paper is on the spectral efficiency (SE) advantages achieved by cooperative transmission and the associated power consumption that may affect the energy efficiency (EE) of the system. A detailed power model is developed to benchmark the various sources of energy consumption in fiber-connected DAS. Then a simple but efficient pre-coding scheme is proposed to reduce the computation complexity associated with cooperative transmission, thus lowering the power consumed by baseband processing while at the same time maintaining a high throughput performance. Through detailed and extensive simulations, this paper demonstrates the SE and EE advantages of the application of fiber-connected DAS in HetNet.
