Signal processing on antenna arrays has received much recent attention in the mobile and wireless networking research communities, with array signal processing approaches addressing the problems of human movement detection, indoor mobile device localization, and wireless network security. However, there are two important challenges inherent in the design of(More)
i n recent years, there has been renewed interest within the mobile and wireless networking communities in addressing problems related to the sensing of signals using multi-antenna radios, such as MIMO Wi-Fi access points. Recent examples include systems that localize RFID tags [8] and Wi-Fi devices [6, 9], enhance Wi-Fi security [10], and passive radar(More)
