| dc.title | Interference management over PRBS in dynamic spectrum refarming | en_US |
| dcterms.abstract | The exponential growth in data traffic is resulting in a spectrum shortage forcing many wireless network operators to look towards refarming their old Second Generation (2G) spectrum and deploy more spectrally efficient Long Term Evolution (LTE) technology.
However, mobile network operators face a challenge when it comes to spectrum refarming because of the inter-technology interference. The deployment of Long Term Evolution
(LTE) provides a better way to meet the increasing demand for high data speeds among the users. However, getting spectrum resource required is a challenge to meet the demand.
The project sought to reduce LTE transmit power on Physical Resource Blocks ( PRBs) near to Global System for Mobile Communication ( GSM ) blocks which also helps to mitigate the impact of GSM on LTE since other non-adjacent PRBs can be allocated more power and partially recover the LTE capacity loss because of GSM overlay. A review of relevant literature revealed that there exist various interference mitigation techniques and explored in great detail the use of relevant software such as MATLAB.
The spectrum that is already used by older technologies can be re-used to deploy new technologies. Such a technique of re-assignment of frequencies from low-value to high- value applications is called spectrum refarming. The refarming intends to use LTE's
flexible bandwidth deployment opportunity to refarm the available spectrum and ensure smooth transition from GSM to LTE which is termed as dyanamic spectrum refarming.
Therefore, the mitigation of interference improves system performance. | |
