Description: 稳健自适应波束形成，Wiley出版社，是一本有关MVDR波束形成稳健性分析的好书。-The latest research and developments in robust adaptive beamforming Recent work has made great strides toward devising robust adaptive beamformers that vastly improve signal strength against background noise and directional interference. This dynamic technology has diverse applications, including radar, sonar, acoustics, astronomy, seismology, communications, and medical imaging. There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids. Robust Adaptive Beamforming compiles the theories and work of leading researchers investigating various approaches in one comprehensive volume. Unlike previous efforts, these pioneering studies are based on theories that use an uncertainty set of the array steering vector. The researchers define their theories, explain their methodologies, and present their conclusions. Methods presented include: Coupling the standard Capon beamformers with a spher Platform: |

Description: 这个例子展示了如何用波束形成来模拟点对点MIMO-OFDM系统。多输入多输出（MIMO）组合和正交频分复用（OFDM）技术已在最近的无线标准的采用，如802.11X，提供更高的数据传输速率。由于MIMO采用天线阵，波束形成可以提高接收信噪比，进而降低误码率。(This examples shows how to model a point-to-point MIMO-OFDM system with beamforming. The combination of multiple-input-multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques have been adopted in recent wireless standards, such as 802.11x families, to provide higher data rate. Because MIMO uses antenna arrays, beamforming can be adopted to improve the received signal to noise ratio (SNR) which in turn reduces the bit error rate (BER).) Platform: |
