In spread spectrum communication systems, it is required to use the spread sequences that have good correlation properties. Complete complementary code is a set of spread sequences, and has ideal auto- and cross-correlation properties. Some previous works have shown that it can be applied into wireless communication systems like approximately synchronized CDMA systems. The authors have proposed a...
An ultra-wideband (UWB) band pass filter with a built-in notch filter is newly proposed. The filter is composed of a conventional multi-layered (ML) composite right-/left-handed (CRLH) transmission line and a super-compact notch filter configured by a ML CRLH unit cell. Two notches created by the notch filter are applied to improve a skirt characteristic of the UWB passband and to reduce interference...
