—Efficient timing synchronization for interleaves must be achieved first before signal detecting and decoding in an IDMA system. However, it is much more difficult to obtain the perfect timing information in IDMA systems than in CDMA systems, owing to the lack of spread gain, especially at the low signal-noise-ratio conditions. In this paper, a conventional(More)
Efficient timing synchronization in an IDMA system must be obtained before signal detection and decoding. However, the research on timing synchronization in IDMA system has not been studied widely. In this paper a new timing acquisition scheme for asynchronous IDMA uplink based on sliding correlation is proposed and its performance in terms of the(More)
Call admission control (CAC) is one of the most important issues for radio resource management of wireless communication systems, which has been widely investigated. However, the computational complexity of the CAC algorithm is still a stringent concern. The performance of interleave-division multiple-access (IDMA) system can be assessed by tracking(More)
A novel polarization receiver for suppressing narrowband interference (NBI) in ultra-wideband (UWB) communication systems is proposed. A null phase-shift polarization (NPSP) filter, consisting of linear polarization vector transformation (PVT), conventional single notch polarization (SNP) filtering, and amplitude and phase compensation (APC), is utilized.(More)
—In order to overcome the shortcomings of existing MAC protocols based on TDMA or CDMA in satellite networks, IDMA technique is introduced into satellite communication networks for the first time, and a novel IDMA-based MAC protocol is proposed in this paper. Due to the potential advantages of IDMA, the proposed scheme avoids complex packet scheduling and(More)
