[AOl15] Improved Successive Stream Selection with Quantized Channel in Heterogeneous Networks
Conférence Internationale avec comité de lecture : The Twelfth International Symposium on Wireless Communication Systems ISWCS 2015, August 2015, pp.1-5, Bruxelles, Belgium,Mots clés: Heterogeneous networks, stream selection, quantized channel, distortion metrics
Résumé:
This paper focuses on different distortion metrics
in order to analyze the influence of the imperfect channel state
information (CSI) on the improved successive stream selection
algorithm that manages the interference in a heterogeneous
network. The presented approach initially selects the streams
from the user of the pico cell, continuing with the strongest
streams among the remaining streams that increase the sum
rate and satisfy the constraint that at least one stream is
selected from each user. In order to reduce the interference,
the channel matrices of the remaining streams are projected
orthogonally to the virtual transmit and receive channels of the
selected stream. The impact of the quantization distortion on the
precoding and postcoding design is examined. The performance
of two distortion metrics which are the Chordal distance and
the Euclidean distance are compared for different number of
quantization bits. The performance evaluations are obtained by
considering different locations of small cells with respect to the
macro cell.
