Green Cellular Wireless Networks: Where to Begin?
Author(s) :
Ayanoglu, Ender
Description :
Conventional cellular wireless networks were designed with the purpose of
providing high throughput for the user and high capacity for the service
provider, without any provisions of energy efficiency. As a result, these
networks have an enormous Carbon footprint. In this note, we describe the
sou...

Common Rate Maximization in Two-Layer Cellular Radio Systems
Description :
We address the common rate maximization problem in two-layer cellular
networks where high-power and low-power base stations are colocated in the same
geographical area. Interference becomes a serious problem when two or more
layers are considered in the same network. For this purpose, power contro...

Interference-Based Cell Selection in Heterogenous Networks
Description :
Heterogeneous cellular networks provide significant improvements in terms of
increased data rates and cell coverage, and offer reduced user rate starvation.
However, there are important problems to be solved. In this paper, we identify
that the cell selection criterion is an important factor deter...

Reduced Complexity Sphere Decoding for Square QAM via a New Lattice Representation
Description :
Sphere decoding (SD) is a low complexity maximum likelihood (ML) detection
algorithm, which has been adapted for different linear channels in digital
communications. The complexity of the SD has been shown to be exponential in
some cases, and polynomial in others and under certain assumptions. The...

Diversity Analysis of Bit-Interleaved Coded Multiple Beamforming
Description :
In this paper, diversity analysis of bit-interleaved coded multiple
beamforming (BICMB) is extended to the case of general spatial interleavers,
removing a condition on their previously known design criteria and quantifying
the resulting diversity order. The diversity order is determined by a para...

Constellation Precoded Beamforming
Description :
We present and analyze the performance of constellation precoded beamforming.
This multi-input multi-output transmission technique is based on the singular
value decomposition of a channel matrix. In this work, the beamformer is
precoded to improve its diversity performance. It was shown previousl...

Bit-Interleaved Coded Multiple Beamforming with Constellation Precoding
Description :
In this paper, we present the diversity order analysis of bit-interleaved
coded multiple beamforming (BICMB) combined with the constellation precoding
scheme. Multiple beamforming is realized by singular value decomposition of the
channel matrix which is assumed to be perfectly known to the transm...

Reduced Complexity Sphere Decoding
Description :
In Multiple-Input Multiple-Output (MIMO) systems, Sphere Decoding (SD) can
achieve performance equivalent to full search Maximum Likelihood (ML) decoding,
with reduced complexity. Several researchers reported techniques that reduce
the complexity of SD further. In this paper, a new technique is in...

Golden Coded Multiple Beamforming
Description :
The Golden Code is a full-rate full-diversity space-time code, which achieves
maximum coding gain for Multiple-Input Multiple-Output (MIMO) systems with two
transmit and two receive antennas. Since four information symbols taken from an
M-QAM constellation are selected to construct one Golden Code...
