在对多输入多输出信遭进行奇异值分解的基础上,推荐了一种新的最小化发射功率的自适应调制算法.通过在不同信道假设条件下的性能仿真,证明了推荐算法能够在满足用户要求服务质量的条件下,以尽可能小的系统发射功率实现数据传输.
A novel adaptive modulation multi-input and multi-output (MIMO) algorithm was proposed, which is based on singular value decomposition of channel matrix and aims at minimizing the overall transmission power. It was proved by the simulations that the proposed algorithm can not only insure the quality of services, but also save much transmission power.
