Impact of small cell user density on performance of small cells sleeping technique for HetNet

Autor: Sultan Aldırmaz Çolak

Publikováno v: Pamukkale University Journal of Engineering Sciences, Vol 25, Iss 5, Pp 519-524 (2019)

In this paper, we analyze the impact of the small cell user density on the power consumption and the number of served users by the macro cell and small cells. It is assumed that users are distributed uniformly in all coverage area with different dens

Autor: Eylem Erdogan, Sultan Aldırmaz Çolak, Hakan Alakoca, Mustafa Namdar, Arif Basgumus, Lutfiye Durak-Ata

Publikováno v: Applied Sciences, Vol 8, Iss 12, p 2486 (2018)

In this work, we examine the interference alignment (IA) performance of a multi-input multi-output (MIMO) multi-hop cognitive radio (CR) network in the presence of multiple primary users. In the proposed architecture, it is assumed that linear IA is

Preamble-Based Symbol Timing Algorithms in OFDM Systems

Autor: Kemal Yağlı, Sultan Aldırmaz Çolak

Publikováno v: The European Journal of Research and Development. 2:445-458

In orthogonal frequency division multiplexing (OFDM) systems, a preamble is added at the start of the OFDM data frame in order to find the correct frame starting point. In the receiver, the symbol starting point is estimated by a correlation-based ti

Optimal Handover Optimization in Future Mobile Heterogeneous Network Using Integrated Weighted and Fuzzy Logic Models

Autor: Waheeb Tashan, Ibraheem Shayea, Sultan Aldirmaz-Colak, Ayman A. El-Saleh, Huseyin Arslan

Publikováno v: IEEE Access, Vol 12, Pp 57082-57102 (2024)

High mobility travelling trains and drones connected via ultra-dense mobile networks may lead to frequent handovers (HOs). As a consequence, this could arise the mobility problems of the serving network such as handover ping-pong (HOPP), radio link f
