This Paper1 investigates the Probability-of-Detection (POD) performance of a novel Wireless Local Positioning System (WLPS2) realized via Direct Sequence Code Division Multiple Access (DS-CDMA) and beamforming techniques. The proposed WLPS has unique signaling schemes that discriminate it from

, however, has been given to the routing protocols which might differ depending on the application and network architecture. In this paper, we present a survey of the state-of-the-art routing techniques in WSNs. We first outline the design challenges for routing protocols in WSNs followed by a comprehensive

In this paper we review the most peculiar and interesting information-theoretic and communications features of fading channels. We first describe the statistical models of fading channels which are frequently used in the analysis and design of communication systems. Next, we focus

Abstract—Downlink beamforming is a promising technique for direct-sequence code-division multiple-access (DS-CDMA) systems with multimedia services to effectively reduce strong interferences induced by high data rate users. In this paper, a new downlink beamforming technique is proposed

This paper deals with blind adaptive multiuser detection and interference cancellation for direct sequence-CDMA wireless communication systems using antenna arrays. Such techniques have recently been considered as powerful methods for increasing overall system quality, capacity and coverage. With a

of sharing the radio spectrum, mutual interference will limit system capacity. Transmitter power control is a well-known method for upholding required signal quality and reducing the energy consumption.

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, "ad-hoc" network topologies, allowing people and devices to seamlessly internetwork in areas with no pre

This paper investigates the implementation of a novel wireless local positioning system (WLPS). WLPS main components are: (a) a dynamic base station (DBS) and (b) a transponder, both mounted on mobiles. The DBS periodically transmits ID request signals. As soon as the transponder detects the ID
