Method of spatial multiplexing in multi-antenna communication systems

Reliability of the communication system with spatial multiplexing has been studied. Increasing bandwidth radio channels due to is one most popular and relevant areas modern research in field communications. Solving problem time domain multipath propagation associated a significant increase dimension redundant calculations. Detection makes it difficult take into account frequency dependence amplitude phase received signals, which turn reduces probability correct signal recognition. In propagation, solution proposed by applying convolution theorem. The error estimated when using detection method. stability depending on conditionality matrix amplitude-phase parameters. expression estimation upper bound subchannel derived number parameters spectral density noise physical channels. An algorithm for adaptive formation matrices developed selects such antennas among an excessive receiving allowing reducing coefficients linear equations. theoretical basis method multi-antenna systems developed. possible efficiency calculations comparison domain. It solve only at frequencies useful expected be received, especially narrow-band phase, orthogonal biorthogonal types modulation often used digital systems. Expressions estimating are derived. developed, problem. results applicable development multiplexing.
