The 11th International Symposium on Wireless Personal Multimedia Communications (WPMC’08) ITERATIVE DATA-AIDED SYNCHRONIZATION FOR MULTIUSER ULTRA-WIDEBAND SIGNALS

چکیده
We propose an iterative synchronizer for chip-interleaved timehopping multiuser ultra-wideband signals subject to intersymbol interference (ISI). The novelty of the design is that it is a soft-input soft-output synchronizerwhich enables to exploit the performance gains of iterative multiuser detection and equalization techniques. The performance of the synchronizer is visualized with simulations, which indicate that it can recover the absence of timing information and catch the performance of a single user ISI-free channel at rather low signal-to-noise ratios.

Multi-carrier code division multiple access (MC-CDMA) is a promising multiple access scheme. An extremely high spectrum efficient transmission technique is required in future wireless communication systems. The use of multiple-input multiple-output (MIMO) space division multiplexing (SDM) is essential to achieve a very high speed data transmission with a limited bandwidth. In this paper, we der...

The Internet protocols were designed to provide end-to-end connectivity across heterogeneous networks, yet primarily assuming a “fixed” and rather static network environment. Mobile and wireless communication have fundamentally invalidated many aspects of these assumptions, for (heterogeneous) wireless access networks and even more so for mobile ad-hoc networks which could be formed between mob...

In this paper we address a promising cross-layer MAC-PHY technique that combines both tree algorithm (TA) for collision resolution and successive interference cancellation (SIC) scheme to recover the signals of collided users. The resulting SICTA protocol family is known to achieve higher throughputs in comparison to the conventional MAC protocols. We concentrate on the performance evaluation o...
