چکیده
This paper presents a novel array processing algorithm for noise reduction in a hands free car environment. The algorithm incorporates the spatial properties of the sound field in a car cabin and a constraint on allowable speech signal distortion. Our results indicate that the proposed algorithm gives substantial performance improvement of 15-20 dB in comparison with the conventional array processing which is based on a coherent model of the signal field.

recently a new structure called groove gap waveguide (GGW) is introduced to implement low loss microwave component devices especially for millimeter wave applications. This paper presents a new type of H-plane horn antenna making use of this new technology in which backward radiation is significantly suppressed by introducing a high impedance surface at the antenna aperture. The high impe...
متن کاملDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
