In this paper, a novel impulsive noise (IN) cancel- lation scheme based on structured compressed sensing (SCS) for multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) power line communication systems is proposed. The SCS theory is introduced to IN recovery for the first time in this paper to the best of the authors' knowledge, and the gap of lack of research on the...
Narrowband interference (NBI) is a major concern that constrains the performance and development of wireless local area network (WLAN) systems. Compressed sensing (CS) is a new and powerful signal processing technique that is applied to solve this problem in this paper. In the framework of structured CS (SCS), we investigated the multiple input multiple output (MIMO) WLAN system, and proposed a novel...
Aiming to achieve wideband and unidirectional radiation, a planar printed antenna with two closely spaced strips is proposed and fabricated. This antenna consists of a printed rectangular loop and two metallic strips. The rectangular loop has a good direction but has a drawback of narrow band. According to the closely spaced loading theory, the impedance at the upper frequency will decrease when the...
