提出了一种在多频时分多址(MF-TDMA,Multi-Frequency Time Division Multiple Access)体制下应用不同调制方式的差分相移键控提供保证服务质量连接的载波信道管理方法。问题分成两个部分——资源的计算和资源的分配。在资源计算阶段,计算保证要求误码率和数据传输速率所需的最小时隙数,误码率直接受链路参数影响,采用马尔科夫模型巧妙地预测连接期间最坏情况下的波动。在资源分配部分,提出了一种预约信道优先算法,通过比较具有比传统分配算法更好的性能。
A method of carrier channel management to ensure quality of service (QoS) connection is proposed using differential phase shift keying (DPSK) with different modulation schemes in a multi-frequency time division multiple access (MF-TDMA) system. The problem is divided into two parts - the calculation of resources and the allocation of resources. In the resource calculation phase, the minimum number of slots required to ensure the required bit error rate and data transmission rate is calculated. The bit error rate is directly affected by the link parameters. The Markov model is used to artfully predict the worst-case fluctuation during the connection. In the resource allocation part, a reservation channel priority algorithm is proposed, which has better performance than the traditional allocation algorithm by comparison.
