A Unified Approach to Multiuser Detection and Space-Time Coding with Low Complexity and Nearly Optimal Performance
نویسندگان
چکیده
Techniques using interleaving as the basic means for signal separation are introduced for both multiple access systems and multiple transmit antenna systems. For multiple access channels, the proposed interleave-division multiple-access (IDMA) scheme can achieve near capacity performance. For multiple antenna systems, the performance of the proposed interleave-division-multiplexing space-time (IDM-ST) codes is close to the socalled canonical performance, which is a theoretical measurement of full transmit diversity. Both IDMA and IDM-ST schemes are characterized by very low receiver complexity and are inherently asynchronous.

Multiuser detection for space-time coded synchronous multiple-access systems in the presence of independent Rayleigh fading is considered. Under the assumption of quasi-static fading, it is shown that optimal (full diversity-achieving) space-time codes designed for single-user channels, can still provide full diversity in the multiuser channel. The joint optimal maximum likelihood multiuser det...

Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
