With the advantages of small size and low cost RSSI-based ranging and positioning technology is suitable for the large-scale applications or indoor environments. Whereas multipath structure of indoor radio channel caused by complex indoor environment, as well as the far field conditions of antennas are not feasible due to the short propagation distance, have a strong impact on indoor positioning accuracy...
Operating at sub-Nyquist rate, compressed sensing (CS) has been successfully applied to the design of impulse ultra-wideband (I-UWB) receivers where Nyquist sampling is a formidable challenge. However, strong narrowband interference (NBI) can easily jam and saturate the receiver front-end and greatly degrade the system performance. In this paper, CS is applied to the design of I-UWB receivers with...
A CMOS circuit is presented which performs all analog interface functions to a standard telephone subscriber line including DC and AC termination, send and receive amplification, anti-side-tone network, line loss compensation, and dialing control. All transmission parameters are software programmable and are loaded into the IC during hook-off or, if necessary, during conversation. It is fabricated...
