Abstract— This paper shows the application of a recently proposed statistical characterization of the ultra-wideband (UWB) radio channel to the standardized IEEE 802.15.4a UWB ph...
— In fast-varying faded channels the transmission can be organized into frames where the channel estimation is mainly training-based. For fast-varying fading channels the trainin...
—In this paper we study the performance of the Ambient Networks (AN) access selection architecture. We consider heterogeneous wireless networks, where mobile terminals (MTs) own ...
Abstract— In wireless sensor networks, one of the big challenges is to achieve a satisfactory network lifetime while meeting quality of service (QoS) requirements. In this paper,...

—The concept of cooperative retransmission in wireless networks has attracted considerable research attention. The basic idea is that when a receiver cannot decode a frame, the r...
Abstract— An optimal admission control (AC) policy is proposed for a CDMA multiple antenna system, which can maximize the system throughput while simultaneously guaranteeing all ...
—Secure routing of Mobile Ad-hoc Networks (MANETs) is still a hard problem after years of research. We therefore propose to design a secure routing protocol in a new approach. Th...

— In this paper we study a simple protocol utilizing two-hop cooperative diversity augmented with “automatic repeat request” (ARQ) for multi-hop ad-hoc networks. This protoco...
— This paper proposes a new approach for decoding LDPC codes over MISO channels. Since in an nT × 1 MISO system with a modulation of alphabet size 2M, nT transmitted symbols are...
