Compressed sensing (CS) is a recent breakthrough in the signal processing area. In this letter, we propose to use the compressed sensing to reconstruct the near-field pattern from a small set of measurements. Results for the near magnetic field recovery on the printed circuit board (PCB) from limited real data and comparisons with the analytical results are provided, showing the validity of the proposed approach in the reduction of the measurement expense.

Microwave pulse Doppler radar systems are useful tools for airplane tracking and velocity estimation in all-weather situations. However, Doppler radar often suffers from intrinsic difficulty when the target Doppler spectrum is buried amongst a cluttered background from clouds as lower pulse repetition frequencies (PRF) cause ambiguity in the Doppler spectrum. To address this issue, we propose a novel target detection method based on the independent component analysis (ICA) scheme. The results from numerical simulations validate the effectiveness of our method compared with those obtained by conventional methods based on principal component analysis (PCA).

Wireless Access in Vehicular Environments (WAVE) communication has been discussed on IEEE 802.11p and established the standard of communication protocol and wireless media, assumed Vehicle-to-Vehicle and Vehicle-to-Infrastructure communications. The present WAVE communication could not fulfill our ITS spot communication systems in performance. Hence, we have developed enhanced WAVE communication devices applicable to spot communications that have a short range of about 10 m. This technological development is characterized by optimizing communication parameters, such as channel coordination and synchronization method. Finally we have confirmed not only devices performance but also the functional fulfillments enough for Electronic Fee Collection systems.

In this letter, a novel compact antenna design for tire pressure monitoring system (TPMS) receiver to operate at 433.92 MHz is presented. This antenna consists of solid inverted-F antenna (IFA), asymmetric co-planar waveguide, tapered-balun and tapered-feeding structure, making it easy to overcome the variable environment. A prototype of the proposed antenna with 75.5 mm in length, 26.5 mm in width and 15 mm in height is fabricated and experimentally investigated. Experimental results are shown to verify the validity of theoretical work.
