英文摘要 | Aimed at the matter about multiuser spectrum allocation of underwater and limited capacity, this paper proposes the dynamic spectrum mechanism of joint power control and channel allocation. Based on the power distribution algorithm of the minimum of outage probability, the author proposed a dynamic spectrum allocation algorithm that combined joint power with channel allocation (JCCA) to maximize the capacity of the underwater acoustic channel. To address these issues about multiuser interference in decoding receiver, this algorithm makes the spectrum allocation optimally when accessing to the authorized spectrum which is limited and maximizing utility function. Simulation results show that the algorithm can save energy. Realize a better multiuser spectrum allocation and increase system capacity when it combines with JPRCPC. |
