| Summary: | Mobile devices are becoming the priority of access to a growing trend of online
services. As services use higher quality images & video, an increase of wireless network
capacity is required. In this case, spectrum is a way to go. Even though capacity is
important, there are other factors as well, for example, coverage, flexibility and
resilience. Dynamic spectrum access technology allows higher transmission power
according to location & safe sharing with licensed users (LU). Dynamic spectrum
allocation (DSA) technique enhances the spectrum efficiency for the users in
Heterogeneous Network. This paper explains about the findings that are observed by two
different researches that are related to our research title. The first paper is about the
basic OFDM structure using GNU Radio software and implemented using USRP
hardware. The second research is about the implementation of Dynamic Resource
Allocation for LTE using GNU Radio. The first research explained about the advantages
and disadvantages of OFDM configuration. The second research explained more about
the implementation of Dynamic Resource Allocation in the uplink and downlink
configuration, and are tested using three algorithms; Max-sum, max-min and maxproduct.
All the results are obtained from GNU Radio. However, the results are not
implemented using USRP because of the short amount of time. Based on these two
researches, we identified the advantages and disadvantages of the proposed designs and
develop our own design to mitigate the cross-tier interference in multi-tiers HetNets. |
