Abstract:

An uplink resource allocation strategy for cognitive single-carrier frequency division multiplexing access (SC-FDMA) system was proposed. After defining the new marginal utility function, the available resource blocks and transmission power were jointly allocated. Simulation shows that although its achieved throughput is slightly lower than other algorithms, on one hand, the proposed algorithm can achieve the continuous resource block allocation, protect the minimal transmission rate for each user very well, and more, avoid the interference to primary network and guarantee the communication of primary network.

Key words: cognitive, uplink resource allocation, minimal transmission rate
