Cognitive Radio (CR) is a promising concept to improve spectrum utilization of the existing spectrum bands. In this paper, spectrum sharing problem between primary users (licensed) and secondary users (unlicensed), who want to use opportunistically the primary users’ spectrum is investigated. One particular form of trading for the spectrum is auction, which is an applied branch of the game theory, and widely known for providing efficient allocation of scarce resources [23]. Sellers use auctions to improve their revenue by dynamic pricing based on demands of buyers. Buyers benefit from auctions since resources would be assigned to those who value them the most. To the best of our knowledge, this paper is the first in which matrix bidding multi unit combinatorial auction is proposed to share the available spectrum of primary user’s among the secondary users. Combinatorial auction is a good candidate to solve spectrum allocation problem since it focuses on providing complementary and substitutable solutions. In the content of this paper combinatorial auction allocate the valuable scarce spectrum to the secondary user on the basis of “bid matrix†submitted by secondary users rather than a single bid. Each channel is considered as a virtual channel comprising of multi slots. Submitting “bid matrix†provides secondary user an opportunity to get multiple slots from different channels in an auction.
