摘要

动态元面天线（DMA）是元面作为有源可重构天线的另一种应用，具有先进的模拟信号处理和波束成形功能，已被提议用于取代下一代收发器的传统天线阵列。受此启发，我们研究了基于 DMA 的系统中的误码概率（BEP）优化问题，提出了一种迭代优化算法，该算法可调整发射前置编码器和 DMA 元素的权重，并证明了其收敛性和复杂性。

On the Bit Error Probability of DMA-Based Systems

Dynamic metasurface antennas (DMAs) are an alternative application of metasurfaces as active reconfigurable antennas with advanced analog signal processing and beamforming capabilities, which have been proposed to replace conventional antenna arrays for next generation transceivers. Motivated by this, we investigate the bit error probability (BEP) optimization in a DMA-based system, propose an iterative optimization algorithm, which adjusts the transmit precoder and the weights of the DMA elements, prove its convergence and derive complexity.
