چکیده

The use of spread spectrum signaling, motivated primarily by its antijamming capabilities in military applications, leads naturally to the use of Code Division Multiple Access (CDMA) techniques that permit the successful simultaneous transmission by a number of users over a wideband channel. In this paper we address some of the major issues that are associated with the design of multiple access protocols for spread spectrum networks. We then propose, analyze, and evaluate a distributed reservation-based multiple access protocol that does in fact exploit CDMA properties. Especially significant is the fact that no acknowledgment or feedback information from the destination is required (thus facUitating communication with a radio-silent node), nor is any form of coordination among the users necessary.

A distributed reservation-based CDMA protocol that does not require feedback information

In some multi-user radio systems the receiver is not allowed to transmit feedback information to the senders. In other applications the transmitters cannot receive feedback information sent by the receiver. For these cases a multiple access protocol is needed that maintains satisfactory performance in the absence of feedback. In this paper, such a protocol is introduced and an exact analysis an...

Photonic Architectures for Distributed Shared Memory Multiprocessors

This paper studies the interaction between the access protocol used to provide arbitration for a wavelengthdivision multiple access photonic network and the cache coherence protocol required to support a distributed shared memory environment. The architecture is based on wavelength division multiplexing which enables multiple multi-access channels to be realized on a single optical fiber. Large...

A Bandwidth Guaranteed Multi-Access Protocol for WDM Local Networks

| In this paper, we propose a bandwidth guaranteed multi-access protocol for broadcast-and-select WDM local networks with a star topology. The proposed protocol is based on a combination of contention and reservation mechanisms for time slotted WDM networks. Every node accesses the data channel by transmitting request packets in minislots on a separate control channel. There are two types of mi...

Selective Tone Reservation method for PAPR reduction in SFBC-OFDM systems

The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

A Novel Multi-user Detection Approach on Fluctuations of Autocorrelation Estimators in Non-Cooperative Communication

Recently, blind multi-user detection has become an important topic in code division multiple access (CDMA) systems. Direct-Sequence Spread Spectrum (DSSS) signals are well-known due to their low probability of detection, and secure communication. In this article, the problem of blind multi-user detection is studied in variable processing gain direct-sequence code division multiple access (VPG D...
