This paper considers iterative frequency-domain receivers for block transmission techniques with rate-1 Space Time Block Coding (STBC) for two and four transmit antennas using both Orthogonal Frequency Division Multiplexing (OFDM) and Single-Carrier (SC) schemes. The proposed receiver includes an interference canceller which enhances the performance of the non-orthogonal STBC scheme with 4 tran...

This paper investigates the performance of the direct approach to connectionless service over ATM. The direct approach utilizes connectionless servers, attached to or incorporated in a subset of the ATM switches, to provide a packet switching service. The number of connectionless servers and ATM connections utilized by the direct approach is found analytically and compared to alternative approa...

ABSTRACT The theoretical foundations of data hiding have been revealed by formulating the problem as message communication over a noisy channel, i.e. the host document. In light of this definition, some solutions have been proposed. Unfortunately, the performances of those methods are limited due to interference with the host signal. Considering spread spectrum information hiding with non i.i.d...

This paper presents a methodology for evaluating the performance of forwarding strategies for location management in a personal communication services (PCS) mobile network. A forwarding strategy in the PCS network can be implemented by two mechanisms: a forwarding operation which follows a chain of databases to locate a mobile user and a resetting operation which updates the databases in the ch...

The present work analyzes and compartes two of the most popular specifications for data transmission over power line networks: PRIME and G3. A complete and detailed description of the specifications together with simulation results of the performance of both solutions in a power line environment are presented. The simulation model has been built using the Matlab workspace. In order to create an...
