Efficient Allocation of TV White Spaces for Cognitive Radio in Pakistan
نویسندگان
چکیده
The spectrum utilization is a function of time and location. Hence, at different times and locations the utilization of spectrum might be different. The TV band 52-862 MHz has been the most crucial frequency band in Pakistan that remains unoccupied most of the time. The unoccupied frequency chunks in the TV band are termed as TV White Spaces (TVWS). In this paper, energy detection technique for spectrum sensing is implemented to locate the TVWS available in Pakistan and overall situation of the spectrum is analyzed. For this purpose, the whole frequency band is scanned with Universal Software Radio Peripheral (USRP2) hardware as well as spectrum analyzer to validate the results of the USRP2 and to investigate the potential of cognitive radios in Pakistan.

TVWS policies to enable efficient spectrum sharing
The transition from analogue to the Digital Terrestrial Television (DTV) in Europe is planned to be completed by the end of the year 2012. The DTV spectrum allocation is such that there are a number of TV channels which cannot be used for additional high power broadcast transmitters due to mutual interference and hence are left unused within a given geographical location, i.e. the TV channels a...
متن کاملSpectrum Sensing with USRP-E110
Spectrum sensing is one of the key topics towards the implementation of future wireless services like SuperWiFi. This new wireless proposal aims at using the freed spectrum resulting from the analog-todigital transition of TV channels for wireless data transmission (UHF TV White Spaces). The benefits range from better building penetration to longer distances when compared to the set of IEEE 802...
متن کاملAn OFDM throughput analysis for cognitive radio application in contiguous or noncontiguous TV white spaces
Radio frequency spectrum is a finite and scarce resource. Efficient use of the radio frequency spectrum is a fundamental research issue. Since a large portion of the assigned radio frequency spectrum is used only sporadically, the bands currently allocated to TV services can be opportunistically reassigned to support broadband networking services while continuing to provide broadcast TV. The fr...
متن کاملCollision Avoidance in TV White Spaces: A Cross-layer Design Approach for Cognitive Radio Networks
One of the most promising applications of cognitive radio networks (CRNs)is the efficient exploitation of TV white spaces (TVWSs) for enhancing the performance of wireless networks. In this paper, we propose a cross-layer design (CLD) of carrier sense multiple access with collision avoidance (CSMA/CA) mechanism at the medium access control (MAC) layer with spectrum sensing (SpSe) at the physica...
متن کاملEffective Deployment of TV White Space for Enhancing Rural Broadband in India
The Radio spectrum has always been a scarce resource right from its initial deployment in 1920s. The television spectrum band is poorly utilized in Indian scenario. Also more efficient spectrum usage is possible with the migration from analogue to digital broadcasting. The use of Cognitive Radios allows an efficient use of the available resources so as to solve the problem of spectrum scarcity....
