摘要

摘要: 为了提高频谱传输效率和抑制信道不确定性影响，该文提出一种基于不完美信道状态信息的认知反向散射通信吞吐量最大化算法。首先，考虑主基站最大发射功率、传输时间、用户服务质量、有界信道不确定性等约束，建立了联合优化主基站波束、传输时间、反射系数的多变量耦合的非线性鲁棒吞吐量最大化模型。其次，利用最坏准则、S-Procedure、连续凸近似和交替优化方法，将原问题转换为凸优化问题，并提出一种基于迭代的鲁棒资源分配算法。仿真结果表明，与非鲁棒算法对比，所提算法具有较好的吞吐量和鲁棒性，且中断概率减小2.39%。

Abstract: To improve spectrum transmission efficiency and suppress the effect of channel uncertainties, a throughput-maximization algorithm is proposed for Cognitive Backscatter Communication with imperfect channel state information. Firstly, considering the constraints of the maximum transmit power of the Primary Base Station (PBS), transmission time, user quality of service, and bounded channel uncertainty, a multivariable coupled nonlinear robust throughput-maximization model is formulated by jointly optimizing the PBS’s beamforming vector, the reflection coefficient and the transmission time. Then, the original problem is transformed into a convex optimization problem by using the worst-case approach, the S-Procedure, successive convex approximation, alternating optimization, and an iteration-based robust resource allocation algorithm is proposed to solve it. Simulation results show that the proposed algorithm has better throughput and robustness compared with the non-robust algorithm, and the outage probability is reduced by 2.39%.

算法1　基于迭代的鲁棒吞吐量最大化算法
初始化系统参数：$ N $, $ M $, $ K $, $T$, $ {\sigma ^2} $, $ {{\boldsymbol{f}}_k} $, $ {{\boldsymbol{f}}_{\text{p}}} $, $ {h_k} $, $ {h_{k,m}} $, $ {P^{\max }} $, $ R_k^{\min } $, $ I_m^{\max } $, $R_{{\text{sum}}}^{\left( 0 \right)}$; ${L_{\max }}$是最大迭代次数，$\eta > 0$是收敛精度，$l = 0$是初始迭代值；
(1) While$\left\| {R_{ {\text{sum} } }^{\left( l \right)} - R_{ {\text{sum} } }^{\left( {l - 1} \right)} } \right\| \ge \eta$或$l \le {L_{\max } }$do
(2) 设置迭代次数$l = l + 1$；
(3) 固定$ \tau _k^{\left( {l - 1} \right)} $和$ \beta _k^{\left( {l - 1} \right)} $，根据式(20)计算$ {\boldsymbol{W}}_m^{\left( l \right)} $。若$ {\boldsymbol{W}}_m^{\left( l \right)} $的秩为1，应用特征值分解法可得到可行解，其中$ {\boldsymbol{W}}_m^{\left( l \right)} = {\boldsymbol{w}}_m^{\left( l \right)}{\boldsymbol{w}}_m^{\left( l \right){\text{H}}} $，若$ {\boldsymbol{W}}_m^{\left( l \right)} $的秩大于1，采用高斯随机化方法求近似解。
(4) 固定$ {\boldsymbol{W}}_m^{\left( l \right)} $，根据式(24)计算$ \tau _k^{\left( l \right)} $，$ \beta _k^{\left( l \right)} $；
(5) 更新吞吐量$R_{{\text{sum}}}^{\left( l \right)}$
(6) End While
