Abstract
In this paper, we study the feasibility of implementing cognitive radio (CR) secondary
network either on the primary Palestinian second generation (2G) global system for mobile
communication (GSM) network or on the ultra-high frequency (UHF) television (TV) band.
Particularly, we propose solutions for spectrum scarcity based on the three CR paradigms,
namely: interweave CR, underlay CR, and overlay CR. In the first solution, an interweave CR
system is suggested to efficiently utilise the so-called TV white spaces in the UHF TV band
allocated for Palestine. In the second solution, an underlay CR system based on code division
multiple access (CDMA) is introduced to underlay the primary GSM system. In the third
solution, an overlay CR system is proposed based on orthogonal frequency division multiplexing
(OFDM) to share the same spectrum band with the primary GSM system. It is confirmed that the
proposed solutions can solve the spectrum scarcity and limit the interference levels, and
consequently improve system capacity.
